Description

Embodiments of the present invention may generally relate to magnetic recording devices, and more specifically to controlling the height and wedge angle of element stripes within a column bar.

A hard disk drive (HDD) is a non-volatile storage device that houses digitally encoded data on one or more circular disks that are housed in a protective enclosure and have a magnetic surface. When the HDD is in operation, each magnetic recording disk is rapidly rotated by the spindle system. Data is read from the magnetic recording disc using a read-write head located on a specific location on the disc by an actuator and written to the magnetic recording disc. The read-write head uses a magnetic field to read data from the surface of a magnetic recording disc and write the data to this surface. The write head uses the current flowing through the coil, which creates a magnetic field. An electrical pulse is sent to the writehead with different patterns of positive and negative currents. The current in the coil of the write head induces a magnetic field across the gap between the head and the magnetic disk, which then magnetizes a small region on the recording medium.

Manufacture of large quantities of magnetic thin film head sliders requires high precision subtractive machining performed in separate material removal steps. The slider process begins with a finished thin film head wafer consisting of over 40,000 devices and is completed when all devices are individualized to meet numerous and stringent specifications. The individual device eventually becomes a read-write head (eg, a Perpendicular Magnetic Recording (PMR) head) for flying over a rotating disk.

Increasing area density (a measure of information bits that can be stored in a given area of the disk surface) is one of the ever-present objectives in evolving hard disk drive design, and one bit. This has led to the necessary development and implementation of various means to reduce the disk space required to record this information. Precise control of the limit dimensions of read and write head elements by machining and wrapping is commonly practiced and essential for manufacturing. What is of continuous importance is the arrangement of the read and write parts of the head relative to each other. Precise dimensional control of the reader and / or writer elements is desirable for optimum yield, performance, and stability.

For example, magnetic core width (MCW) (and magnetic erase width (MEW), magnetic write width (MWW), magnetic interference width (MIW), and others. Improvements in the process with respect to the relevant magnetic core means) are beneficial to the surface density as the MCW effectively determines the width of the magnetic bits recorded by the write head. Furthermore, the single largest contributor to the overall MCW sigma is typically the "in-row bar" sigma. Some thin films and other manufacturing processes (eg, lithography, even if the manufacturing process is developed to manufacture a read-write head with an MCW that is as close as possible to the desired MCW in the system. Etching, coarse wrapping, material elasticity, etc.) experience inherent changes that make it very difficult to achieve the desired MCW of any read-write head manufactured.

The techniques described in this section are techniques that can be pursued, but not necessarily previously devised or pursued. Therefore, unless otherwise indicated, none of the methods described in this section should be assumed to simply qualify as prior art by including them in this section.

Physical description of the exemplary operating environment

Embodiments can be used in the context of read-write heads for digital data storage devices (such as hard disk drives (HDDs)). Thus, according to the embodiment, a plan view showing the HDD 100 is shown in FIG. 1 to show an exemplary operating context.

FIG. 1 shows the functional arrangement of components of the HDD 100 including a slider 110b including a magnetic read-write head 110a. Collectively, the slider 110b and the head 110a may be referred to as head sliders. The HDD 100 was attached to at least one head gimbal assembly (HGA) 110 including a head slider, a lead suspension 110c typically attached to the head slider via a flexor, and a lead suspension 110c. The load beam 110d and the like are included. The HDD 100 also includes at least one recording medium 120 rotatably mounted on the spindle 124 and a drive motor (invisible) mounted on the spindle 124 to rotate the medium 120. The read-write head 110a, which may also be referred to as a converter, includes a write element and a read element for writing and reading the information stored in the medium 120 of the HDD 100, respectively. The medium 120 or a plurality of disc media may be fixed to the spindle 124 with a disc clamp 128.

The HDD 100 includes an arm 132 attached to the HGA 110, a carriage 134, a voice coil motor (VCM) including an armature 136 including a voice coil 140 attached to the carriage 134, and a voice coil magnet (invisible). The stator 144 including the above, and the stator 144 including the above. The armature 136 of the VCM is attached to the carriage 134 and is configured to move the arm 132 and the HGA 110 and access the portion of the medium 120, all together in the intervening pivot bearing assembly 152. It is mounted on the pivot shaft 148. In the case of an HDD having a plurality of disks, the carriage 134 may be referred to as an "E block" or a comb because the carriage is arranged to carry an interlocking arm array that gives the carriage the appearance of a comb.

A head gimbal assembly comprising a flexure to which a head slider is coupled, an actuator arm to which the flexor is coupled (eg, arm 132) and / or a load beam, and an actuator to which the actuator arm is coupled (eg, VCM). An assembly comprising (eg, HGA110) may be generically referred to as a head stack assembly (HSA). However, the HSA may contain more or less components than those described. For example, HSA can refer to an assembly that further includes electrical interconnect components. Generally, the HSA is an assembly configured to move the head slider to access a portion of the medium 120 for read and write operations.

Further referring to FIG. 1, the electrical signal including the write and read signals from the head 110a (eg, the current of the VCM to the voice coil 140) is a flexible cable assembly (FCA) 156 (or Sent by "flex cable"). The interconnection between the flex cable 156 and the head 110a may have an onboard preamplifier for the read signal, as well as other read and write channel electronic components, arm-electronics (AE). Module 160 may be included. The AE module 160 may be attached to the carriage 134 as shown. In some configurations, the flex cable 156 may be coupled to an electrical connector block 164 that provides telecommunications through the electrical feedthrough provided by the HDD enclosure 168. The HDD housing 168 (or "enclosure base" or simply "base"), along with the HDD cover, is a semi-sealed (or airtightly sealed) protection for the information storage components of the HDD 100. Provide an enclosure.

Other electronic components, including disk controllers and servo electronics, including digital-signal processors (DSPs), provide electrical signals to drive motors, VCM voice coils 140 and HGA110 heads 110a. The electrical signal provided to the drive motor allows the drive motor to rotate while providing torque to the spindle 124, which is then transmitted to the medium 120 attached to the spindle 124. As a result, the medium 120 rotates in the direction 172. The rotating medium 120 has an air-bearing surface (ABS) of the slider 110b so that the slider 110b floats above the surface of the medium 120 without contacting the thin magnetic recording layer on which the information is recorded. Form a cushion of air that acts as a riding air bearing. Similarly, in HDDs where a gas lighter than air, such as helium, is used as a non-limiting example, the rotating medium 120 forms a cushion of gas on which the slider 110b rides or a gas acting as a fluid bearing.

The electrical signal provided to the voice coil 140 of the VCM allows the head 110a of the HGA 110 to access track 176 on which the information is recorded. Thus, the armature 136 of the VCM swing through the arc 180 allows the head 110a of the HGA 110 to access various tracks on the medium 120. The information is stored on media 120 in a plurality of radial nested tracks arranged in sectors on media 120, such as sector 184. Correspondingly, each track is composed of a plurality of sectorized track portions (or "track sectors"), such as a sectorized track portion 188. Each sectorized track portion 188 may include recorded information, error correction code information, and a header that includes a servo burst signal pattern such as the ABCD servo burst signal pattern that is information that identifies the track 176. .. When accessing track 176, the reading element of the head 110a of the HGA 110 reads the servo burst signal pattern, which provides the servo electronics with a position-error-signal (PES) and the servo electronics. The device allows the head 110a to follow the track 176 by controlling the electrical signal provided to the voice coil 140 of the VCM. Upon finding track 176 and identifying a particular sectorized track portion 188, head 110a reads information from track 176 or is received by a disk controller from an external agent, eg, a microprocessor in a computer system. Information is written to track 176 in response to the instruction.

The electronic architecture of an HDD is its own function for HDD operation, such as hard disk controller (“HDC”), interface controller, arm electronic module, data channel, motor driver, servo processor, buffer memory, etc. Includes a number of electronic components to perform. Two or more of such components may be combined on a single integrated circuit board called a "system on a chip". Some, but not all, of such electronic components are typically located on a printed circuit board coupled to the bottom side of the HDD, such as the HDD enclosure 168.

References to hard disk drives herein, such as the HDD 100 shown and described with reference to FIG. 1, may include information storage devices, sometimes referred to as "hybrid drives." A hybrid drive is generally a solid-state storage device (SSD) that uses non-volatile memory such as an electrically erasable and programmable flash or other solid state (eg, integrated circuit) memory. Refers to a storage device having both functions of a conventional HDD (see, for example, HDD 100) combined with. Since the operation, management, and control of different types of storage media are usually different, the solid-state portion of the hybrid drive may include its own corresponding controller function, which is combined with HDD function into a single controller. Can be integrated. As a non-limiting example, a hybrid drive uses a solid state memory as a cache memory for storing frequently accessed data, storing I / O aggregated data, etc., and thus a solid state part. May be designed and configured to operate and utilize in several ways. In addition, the hybrid drive may be essentially designed and configured as two storage devices in a single enclosure, namely conventional HDDs and SSDs, with any one or more interfaces for host connectivity.
Introduction

It will be understood that the term "substantially" describes features such as most or almost structured, structured, dimensioned, etc., but its manufacturing tolerances etc. are in fact Can result in situations where the structure, configuration, dimensions, etc. are not always or necessarily accurately stated. For example, if the structure is described as "substantially vertical," the term is obvious, as the sidewalls are vertical for all practical purposes, but may not be exactly 90 degrees. Meaning is assigned.

As mentioned above, it is typically the "in-row bar" sigma that contributes most to the overall magnetic core width (MCW) sigma, with a read having an MCW as close as possible to the target MCW- Even when developed to manufacture write heads, some thin film processes experience inherent variability that continually makes it difficult to achieve the target MCW of any head manufactured. ..

Furthermore, the fabrication of large quantities of magnetic thin film head sliders requires high precision subtractive machining performed in separate material removal steps. The slider process begins with a finished thin film head wafer consisting of over 40,000 devices and is completed when all devices are individualized to meet numerous and stringent specifications. The individual device eventually becomes a head slider that houses the read-write head. Therefore, in order to achieve optimum yield, performance, and stability, precise control of the dimensions of the reader and the arrangement of the reader and writer relative to each other is an important component of the read-write head manufacturing process. Is. In order to achieve the ideal dimensions of the individual read-write heads, one may choose to process each head slider individually. However, that approach is nearly impossible from a practical manufacturable point of view, as it results in, for example, a significantly complex, inefficient, and costly head slider manufacturing process.

FIG. 2 is an exploded perspective view illustrating the wafer of the head slider at various stages of processing, and FIG. 2A is a perspective view illustrating a read-write transducer, both of which are by embodiment. FIG. 2 represents a wafer 202 comprising a matrix of unfinished head sliders with unfinished read-write transducers (see FIG. 2A) deposited on a substrate 203 in which AlTiC is commonly used. The slider matrix is typically processed in batches, or subsets of wafers, historically referred to as "quads" and now sometimes referred to as "chunks" or "blocks". A block of unfinished head sliders, block 204, comprises multiple rows of unfinished head sliders 206a-206n (or "row bars"), where n is per block 204, which can vary from implementation to mounting. Represents the number of column bars. Each row 206a-206n comprises a plurality of head sliders 208a-208m, where m represents the number of head sliders per row 206a-206n that may vary from implementation to mounting.

Referring to FIG. 2A, the read-write transducer 210 comprises a write device element 212 (or simply "write device 212") and a corresponding coil 216. The write head uses a current flowing through a coil such as coil 216 to generate a magnetic field. Electrical pulses are transmitted to the writehead in different patterns of positive and negative currents, and the current in the coil of the writehead induces a magnetic field across the gap between the head and the magnetic disk, which is then placed on the recording medium. Magnetizes a small area of. A writing device such as the writing device 212 has a corresponding flare point 213, which is (a) the end of the main pole of the writing device (ie, the end of the pole tip 220) and the pole tip 220. It is the distance between the point (b) 221 extending to the minimum cross section. The flare point 213 is generally considered to be the critical dimension associated with a magnetic writing device such as the writing device 212.

Continuing with FIG. 2A, the read-write transducer 210 further comprises a reader element 214 (or simply "reader 214") having a corresponding stripe height of 215, which is also a magnetic read of the reader 214 and the like. It is considered the limit dimension associated with the device. The flare point 213 of the writing device 212 and the stripe height 215 of the reading device 214 are not limited, but with wedge angle wrapping (“WAL”) as described in more detail herein (see FIG. 3 and the like). It is commonly controlled during production by a so-called "coarse wrap" process.

A read-write transducer, such as the transducer 210, is further associated with a read-write offset 217 (or "read-write offset" or read-write offset, "RWO"), which offset is specific to the reader 214. The distance between a point or surface and a particular point or surface of the writing device 212, expressed as the y direction. The RWO217 is designed within the read-write transducer 210. However, during the fabrication of wafer 202, an uncontrollable (and undesirable) offset may occur between the writer 212 and the reader 214, which varies along the column represented as the x direction. Possible linear offsets and / or angular offsets can occur. Such any offset is primarily due to the writing device 212 and reading device 214 being placed in different thin film layers and therefore due to manufacturing process limitations. For example, the writer 212 and the reader 214 with respect to the air bearing surface and / or each other due to problems associated with exposing different masks with different patterns in different sedimentary layers in the nanometer scale manufacturing process. On the other hand, it may not always be aligned accurately.

As a result, the RWO produced at the wafer level may not be exactly the target RWO. Therefore, the WAL (or "RWO angle") process described above is typically utilized to align the column bar RWO closer to the target RWO. However, the coarse wrapping WAL process described above can typically only reach a correction level of about 5 nm and is typically applied "per column bar" rather than "per slider". NS. Therefore, finer and more accurate wrapping procedures can be considered useful.
Head slider manufacturing process-general

A typical head slider manufacturing process flow is a wafer (eg, wafer 202 in FIG. 2) manufacturing process involving the deposition of reader and writer elements (eg, reader 214 and writer 212 in FIG. 2A), followed by a wafer (eg, wafer 202 in FIG. 2) manufacturing process. Subsequent blocks (or "quad") slices for removing unfinished slider blocks (eg, block 204 in FIG. 2) from the wafer can be included. The outer row (eg, row 206a of FIG. 2) of the slider from the block (eg, head slider 208a-208 m in FIG. 2) is then coarsely wrapped (eg, wedge angle wrapped) to obtain the desired reader and device. Manufactured to be close to the dimensions of the writing device (eg, flare point 213 and stripe height 215 in FIG. 2A), then a coarsely wrapped row (eg, row 206a) outside the block (eg, block 204). Can be sliced. From there, the rows are further wrapped, such as by "back wrapping" to form a flexure side surface facing the air bearing surface (ABS), and then "fine wrapping" (or "final wrapping"). ), And the ABS surface can be further polished. This can then lead to overcoating of the ABS surface and rail etching, etc., to form the final air bearing or flight surface, at which point each head slider (eg, head slider 208a-208 m), The rows can be diced or split into individual finished head sliders, which can then be combined with flexures, assembled into head gimbal assemblies (HGA), and the like.
Wedge angle wrapping

As discussed, the flare point 213 (FIG. 2A) of the writing device 212 (FIG. 2A) and the stripe height 215 (FIG. 2A) of the reading device 214 (FIG. 2A) are not limited, but wedge angle wrapping (“WAL”). ), Which is commonly controlled during production. By "passive WAL control", the column bars are often wrapped to a predetermined wedge angle ("WA") based on offline electrical test measurements, thereby causing the WA to be wrapped to a physical target angle. Be controlled. Alternatively, by "active WAL control", the column bar becomes a resistor (eg, from the use of electronic lapping guides or electronic lapping feedback, "ELG" associated with the reader and / or writer elements). Based on feedback, it is servoed or controlled to the desired RWO. In either case, an average or intermediate WA is targeted for the entire column bar, without individual control of the head sliders within the column bar.

FIG. 3 is a diagram illustrating a wedge angle wrapping (WAL) process, such as in a rough wrap step. The figure on the left side of FIG. 3 represents the head slider 302 before rough wrapping the air bearing surface (“ABS”). The reading device 214 and the corresponding desired stripe height 215 are represented, the wrapping of which is typically controlled via a resistance-based feedback mechanism, as described above, and the writing device 212. And the corresponding resulting flare point 213 is also represented. The dashed line illustrates the desired final ABS, which is achieved by wrapping the ABS side of the head slider 302 at a wedge angle 303.

Therefore, referring to the figure on the right side of FIG. 3, ABS wrapping is represented in a simplified form with a wrapping jig 304 and a wrapping plate 306 (eg, commonly accompanied by diamond studded and / or diamond slurry). Can be performed on the head slider 302 using. The jig 304 operates the wrapping plate 306 to wrap the head slider 302 at a wedge angle 303 until it finally reaches the dimensions of the target reading device 214 and writing device 212, whereby the head slider manufacturing process. It is set to achieve a read-write head with at least the desired stripe height of 215 for this particular portion of the.

Wedge angle wrapping is typically performed on all column bars of the slider, such as any of columns 206a-206n (FIG. 2), at a particular predetermined wedge angle. Therefore, each slider 208a-208m (FIG. 2) in a given row is roughly wrapped at the same wedge angle, such as wedge angle 303 (FIG. 3). However, as mentioned above, there may be an undesired offset (s) between the writing device 212 (FIG. 2A) and the reading device 214 (FIG. 2A) during the fabrication of wafer 202 (FIG. 2). This offset can give rise to linear and / or angular offsets in one or more directions. Furthermore, such offsets (s) corresponding to the write device 212 and the read device 214 may also be along the length (x direction) of any given row (eg, row 206a) of the head slider. It may not be constant even from a block (for example, block 204 in FIG. 2) to a plurality of columns (for example, columns 206a to 206n). Again, there is a reason why it may be preferable to process the head sliders individually when it is actually possible.

4A, 4B are diagrams illustrating a rigid bond WA wrapping process that may be applicable to the scenario represented in FIG. FIG. 4A represents a "snapshot" of a series of coarse wrap WAL processes, where each snapshot is separated by a vertical dashed line, in which a rigid adhesive bond 403 is used to provide an unfinished head slider 402. It is temporarily joined to the rigid touring jig 404. At the top of FIG. 4A, the head slider 402 is gradually wrapped at a first wedge angle a using a wrapping plate 406, thus the fabrication of the head slider 402-1 is a polygon of the first quadrilateral. It is recognized that it is represented as having a polygonal shape. Wrapping at the wedge angle may entail the goal of achieving a particular target stripe height for the reader, such as stripe height 215 for reader 214 in FIG. 2A. Referring to FIG. 4B, when the wrapping proceeds through the WAL process and reaches the head slider 402-1, the progress of material removal of the head slider 402 is uniform (ie, at a constant angle) at a constant wedge angle a. Is recognized.

At the bottom of FIGS. 4A, 4BA, the head slider 402-1 is gradually wrapped at a second wedge angle β, subsequently using the wrapping plate 406, so that the fabrication of the head slider 402-2 is the first. It is recognized that it has two quadrilateral polygonal shapes. This wrapping to a constant wedge angle β is equally uniform as the wrapping proceeds through the WAL process and reaches the head slider 402-2. It is noteworthy that in the current practice, the wedge angle adjustment can typically be made only once or twice during the rough lap WAL process shown in FIGS. 4A, 4B. Furthermore, the use of a constant wedge angle can produce facets (s) within the head slider, even when adjusted by 1 or 2 degrees (best represented by the head slider 402-1). ). Furthermore, this coarse wrap WAL process targets the stripe height of the reader element (such as the stripe height 215 of the reader 214 in FIG. 3) and obtains wrapping feedback via the reader or writer ELG. It is worth noting that the flare points and RWO217 (FIG. 2) of the writer element (such as the flare point 213 of the writer 212 in FIG. 3) are relatively uncontrolled. ..
Wedge angle wrapping wrapping tool in row

FIG. 5 is a bottom side perspective view illustrating the wrapping tool, and FIG. 6 is a bottom front perspective view illustrating the wrapping tool of FIG. 5, both of which are based on an embodiment. The wrapping tool 500, according to embodiments, comprises a box structure 502 that is rotatable and / or flexible. The box structure 502 includes a front side 504 that accommodates a plurality of force pins 505 that are substantially movable in the z direction, and a rear wall 506.

The wrapping tool 500 is a jig for holding the row bar 206 of the magnetic read-write head slider so that each of the plurality of force pins 505 is positioned to apply a force to the corresponding head slider of the row bar 206. 508 is further provided. The wrapping tool 500 provides at least two flexibility that interconnects the second rear wall 510 at a distance from the rear wall 506 of the box structure 502 and the rear wall 506 and the second rear wall 510 of the box structure 502. Wedge angles (WA) flexors 512a and 512b (three are represented together with WA flexures 512c) are further provided. In particular, the WA flexors 512a, 512b, and 512c virtually intersect at a rotation axis centered on the x-axis associated with the column bar 206, thus defining this rotation axis (see FIGS. 7, 7A). Represented and explained in more detail). Therefore, depending on the operation of the WA flexors 512a, 512b, 512c and based on their virtual intersections, each force pin 505 has a rotation axis defined by the virtual intersections of the WA flexors 512a, 512b, 512c. At the center, torque is applied to its corresponding head slider.

Based on the above-mentioned interaction structure of the wrapping tool 500, each head slider of the row bar 206 (eg, FIG. 2) wraps an independent and variable wedge angle (with respect to the y-axis direction) to each target wedge angle. Head sliders 208a to 208m) can be set. In practice, the plurality of force pins 505 twist the row bars 206 together in response to actuation, setting each head slider of the row bars 206 for parallel wrapping in parallel with their respective target wedge angles. ..

According to the embodiment, the wrapping tool 500 transmits each force pin 505 to the corresponding head sliders 208a-208 m in order to transmit a torque-corresponding y-direction pressure gradient (eg, pressure gradient 904a in FIG. 9A) from the force pins 505. A flexible elastomer 516 is further provided between the 505 and its corresponding head slider of the row bar 206 (eg, head sliders 208a-208 m in FIG. 2). Therefore, the material removal associated with each head slider 208a-208m by wrapping corresponds to the pressure gradient 904a applied to each head slider 208a-208m.

According to embodiments, the material of elastomer 516 has a Shore A hardness in the range of 10 to 90 durometers, which is found to be suitable for the intended purpose. For example, a flexible elastomer 516 (rather than a rigid bond such as the rigid adhesive bond 403 in FIG. 4A), as a non-limiting example, a silicone or polyurethane rubber (eg, 0.05-1.5 mm thick, for its intended purpose). The use of (to the extent found to be suitable) effectively eliminates the action of the head slider lifting from the wrapping plate and the associated head slider fasetting that can occur with the rigid bond of FIG. 4A. Furthermore, the thicker the elastomer 516, the softer the cushion provided between the force pins 505 and the head sliders 208a-208 m (FIG. 2), and thus the finer of the pressure gradient 904a over each head slider 208a-208 m. Control is achieved. That is, the actuation of the force pins 505 and the response corresponding to their effect on the head sliders 208a-208m are effectively diminished. Similarly, the harder the elastomer 516, the more rapid the response corresponding to the more rapid action of the force pins 505 and their effect on the head sliders 208a-208m (ie, this response is less diminished and more). Finer control of operation must be provided for gradual change). Therefore, the effective resolution of the pressure gradient 904a across each head slider may vary from implementation to implementation based on the choice of material used for the flexible elastomer 516.

The wrapping tool 500 further comprises at least two stripe height (SH) flexors 514a and 514b interconnecting the front side 504 and the rear wall 506 of the box structure 502. Considering the structural support provided by the SH flexors 514a and 514b throughout the box structure 502, each force pin 505 has a target stripe for each reader (such as stripe height 215 for reader 214 in FIG. 2A). A force in the z direction can be applied to the corresponding head sliders of the row bar 206 (eg, head sliders 208a-208 m in FIG. 2) so as to wrap to height. Therefore, based on the above-mentioned interaction structure of the wrapping tool 500, each head of the row bar 206 wraps the target stripe height of the independent (with respect to the z-axis) reader to its respective target stripe height. Can be set on the slider.
Wrapping tool wedge angle flexure

7 is a side sectional view illustrating the wrapping tool of FIGS. 5 to 6, and FIG. 7A is a side sectional view illustrating the jig of the wrapping tool of FIG. 7, both of which are according to an embodiment. .. 7 and 7A are referenced to illustrate WA flexors 512a, 512b, 512c (FIGS. 5-6) in more detail.

FIG. 7 illustrates the wrapping tool 500 and components according to the embodiments described with respect to FIGS. 5-6. 7 and 7A are such that the WA flexors 512a, 512b (and 512c) "virtually" intersect at a rotation axis around the x-axis associated with the column bar 206, thus defining this rotation axis. Further, at least two wedge angle (WA) flexors 512a, 512b (and optional 512c) interconnecting the box structure 502 and the rear wall 510 of the second rear wall 510 are positioned and configured. Illustrate. Unless otherwise stated, WA flexors 512a, 512b (and 512c) are all (in the x direction) axes of rotation when they extend through the rear wall 506 and front side 504 of the box structure 502. It is positioned to intersect at the point that defines. Torque is applied to the head slider (eg, 208a-208m in FIG. 2) by activating the corresponding force pin 505 around the axis of rotation, thus effectively rotating the box structure 502. Recall that the torque appears as a pressure gradient 904a applied over the corresponding head slider length (y direction) when transmitted through the flexible elastomer 516. Therefore, this independently and variably applied pressure gradient 904a provides WA wrapping control (represented as block arrow 702) centered on a common axis of rotation for each head slider. An accurate, independent, and dynamically variable ( That is, wedge angle control (by varying the operation of force pin 505) is provided to row bar 206 for each head slider component.

7 and 7A further illustrate stripe height (SH) wrapping control (represented as block arrow 704), the use of which is described with reference to the method of wrapping the column bar of FIG.
How to Wrap Column Bars on Magnetic Read-Write Head Sliders

FIG. 8 is a flow chart illustrating a method for wrapping the row bar of the head slider according to the embodiment. The various embodiments described with respect to FIG. 8 can each be performed using the wrapping tool 500 (FIGS. 5-7) described elsewhere herein. For context and as described, each column bar has an x-axis along the direction of the column and a y-axis along the direction of the reader-writer offset associated with the head slider in the column bar. Each head slider comprises a reading device element and a writing device element.

At block 802, the row bar of the magnetic read-write head slider is secured to the wrapping tool jig. For example, the row bar 206 (FIGS. 5, 6, 7A) is a jig 508 (FIG. 5, FIG. 7) of the wrapping tool 500 (FIGS. 5-7A) via an elastomer 516 (FIGS. 5, 6, 7A) and the like. It is fixed to 5 to FIG. 7A). The stickiness of the elastomer 516 material affects the ability of the elastomer 516 to hold the row bars 206 in place on the jig 508. Therefore, the adhesiveness of the elastomer 516 can vary from mounting to mounting.

At block 804, each of the multiple force pins of the wrapping tool is activated to set each head slider on the row bar to wrap to its respective target wedge angle. For example, each force pin 505 may be actuated (by pneumatic, hydraulic, mechanical, electrical, etc., as a non-limiting example) to bring each head slider 208a-208 m of row bar 206 (FIG. 2). Each target wedge angle 303 (FIG. 3), which is an angle with respect to the y-plane along the y-axis, is set. The mode in which each respective target wedge angle is set is consistent with that described herein with reference to FIGS. 5-7A.

Therefore, at block 806, each head slider is wrapped simultaneously according to each corresponding target wedge angle. For example, each head slider 208a-208m of the row bar 206 is wrapped according to each corresponding target wedge angle 303. It is recalled from FIG. 3 that wrapping can be performed on the head slider or row bar of the head slider using a wrapping jig 304 and a wrapping plate 306 commonly studded with diamonds and / or with a diamond slurry. sea bream.

9A, 9B are diagrams illustrating a "soft" bond WA wrapping process according to an embodiment. Further refer to FIGS. 4A and 4B to compare the soft bond WA wrapping process of FIGS. 9A and 9B with the rigid bond WA wrapping process of FIGS. 4A and 4B. FIG. 9A represents a “snapshot” of a series of “fine wrap” (or “final wrap”) WAL processes (each snapshot separated by a vertical dashed line), which is incomplete with the flexible elastomer 516. The head slider 902 of the above is temporarily joined to the rigid touring jig 508. In the first snapshot, it is recognized that an appropriate pressure gradient 904a to be applied to the head slider 902 is determined, at least to begin achieving the target wedge angle. For the slider 902, the corresponding force pins 505 (FIGS. 5-6) apply torque to the wrapping tool jig 508 and to the head slider 902 through the elastomer 516 to provide the desired pressure over the length of the head slider 902. A gradient 904a is generated. Note that the figure of FIG. 9A is simplified in that the elastomer 516 has a sharp line at the interface with the head slider 902, for example, as if a portion of the elastomer 516 had been cut off. I want to be. However, the elastomer 516 compresses in response to torque (rather than being cut off), whereby the torque is greater within the elastomer 516 relative to the distance away from the axis of rotation (or the center of torque) in the direction of torque. Please be aware that it causes compression. Similarly, torque causes less compression in the elastomer 516 relative to the distance from the axis of rotation (or the center of torque) in the direction opposite to the direction of torque. Therefore, the pressure gradient 904a is represented from smaller to larger in the right-to-left direction. As a result, more material, given the increasing point pressure (due to the pressure gradient 904a) applied to the head slider 902 over that length and the head slider interlocking with the rigid wrapping plate 406. Is removed from the slider according to the pressure gradient 904a (ie, from left to right).

With reference to FIG. 9B, by applying the pressure gradient 904a to the head slider 902, it is recognized that the progress of material removal on the head slider 902 is not at a constant angle as the wrapping progresses through the WAL process. Since there is some pressure over the entire length of the slider, the pressure changes according to the pressure gradient 904a, but the progress of material removal is different from that due to the rigid bond and constant wrapping angle as shown in FIG. 4B. As shown in FIG. 9B, the application of the pressure gradient 904a changes the wrapping angle as the material is gradually removed from the surface of the head slider 902.

The second (center) snapshot shows that a slightly different pressure gradient 904b is applied to the head slider 902 and continues to achieve the target wedge angle, such as by servo control changes when the target wedge angle is reached. .. Therefore, the wrapping systems and methods described herein provide a dynamic change in wedge angle for each head slider by a controlled feedback system (eg, an ELG feedback system). The wedge angle can be changed dynamically by changing the working profile of the force pin 505 during the wrapping process, whereby the wrapping system is dynamically servoed to achieve the desired result. Rather than using a constant rigid wedge angle, it is possible to generate facets (s) within the head slider by using a gradual change in wedge angle by applying a pressure gradient with an elastomer. It is worth noting that it will be much lower.

Returning to the flow diagram of FIG. 8, the optional blocks 808 set each head slider of the row bar to activate each of the plurality of force pins to wrap to the respective reader target stripe height. For example, each force pin 505 is servo- or discretely actuated (by pneumatic, hydraulic, mechanical, electrical, etc., as a non-limiting example) and each head slider 208a-208m of row bar 206. (FIG. 2) is set to the target stripe height 215 (FIGS. 2A, 3) of each reading device.

Continuing, the optional blocks 810 wrap each head slider simultaneously according to their respective corresponding target stripe heights. For example, each head slider 208a-208m of the row bar 206 is wrapped according to the target stripe height 215 of each corresponding reading device 214 (which can be based on the reading device ELG and / or the writing device ELG stripe height). Returning to FIG. 9A, in the third snapshot, the torque across the head slider and the resulting pressure gradient 904a (and 904b) are interrupted (eg, the target wedge angle has been reached), and at this point. A relatively (or "substantially") constant pressure of 904c is applied over the length of the head slider 902, indicating that at this point it wraps around the stripe height 215 of the target reader 214.

Thus, according to embodiments, and as described elsewhere herein, this soft (fine), as opposed to the rigid bond (coarse) wrapping process represented in FIGS. 4A, 4B. The wrap WAL process first wraps to the target wedge angle and then to the stripe height of the target reader or writer, thereby including control of the RWO (such as RWO 217 in FIG. 2). Provides control of the degree of. It is also conceivable to correct the process for the first lap towards the target stripe height and the next lap to the target wedge angle, and is within the scope of the embodiments described herein.
Wrapping mount tool for stripe height / flare point and wedge angle wrapping in rows

10A is a front side perspective view exemplifying the wrapping mount tool, FIG. 10B is a front top perspective view exemplifying the wrapping tool of FIG. 10A, and FIG. 10C is a bottom side exemplifying the wrapping tool of FIG. 10A. It is a perspective view, and all are according to the embodiment. Unless otherwise noted, many of the functional and operational concepts described in the context of the Wrapping Tool 500 can be similarly applied to the Wrapping Mount Tool 1000 of FIGS. 10A-10C.

The wrapping mount tool 1000 comprises a first structural member 1002 that, according to embodiments, is rotatable and / or flexible. The first structural member 1002 includes at least a plurality of angle actuating pins 1005, or forks 1003 (as a non-limiting example, a two-blade fork), each of which has a V-shaped notch (“V notch”). Contained at the top for the purpose of operation. According to embodiments, the first and last "pin" structures of the first structural member 1002 are structurally different from the inner angle actuating pin 1005 and are represented to be wider and also primarily the inner twist. Note that it serves to protect the fragile angle actuating pin 1005. However, the Wrapping Mount Tool 1000 does not intend the first and last "pins" of the first structural member 1002 to interact with the corresponding head sliders, much like most of the angle actuating pins 1005. If the pin is omitted from the tool, it is still operational for its intended purpose. According to embodiments, and as represented, adjacent forks 1003 (eg, fork combs) can be staggered alternately in the z direction, which is such spatially constrained. Facilitates engagement between the actuating mechanism and the corresponding fork 1003 in the environment. However, according to embodiments, the group of forks 1003 can be configured linearly rather than staggered, as represented. The first structural member 1002 is positioned such that each of the plurality of angle actuating pins 1005 applies an angle wrapping force to the corresponding head slider of the row bar 206 in response to actuation (eg, "second actuation"). A jig 1008 for holding a row bar of a magnetic read-write head slider (eg, rows 206a-206n in FIG. 2; generally "row bar 206") is provided.

The wrapping tool 1000 includes a first flexible wedge angle (WA) flexor 1012a (“first flexure”) and a second flexible wedge angle (WA) flexor 1012b (“second flexure”). Further comprises a second structural member 1006 displaced and coupled to the first structural member 1002 via or by them. The second structural member 1006 accommodates a plurality of stripe height (SH) actuating pins 1007, each positioned to apply a wrapping force to the corresponding head slider of the row bar 206. According to embodiments, similar to the outer "pin" structure of the first structural member 1002, the second structural member 1006 first and last "pin" structures are structurally similar to the inner SH actuating pin 1007. Differently represented as wider, it also primarily serves to protect the inner, more fragile SH actuating pin 1007. However, the Wrapping Mount Tool 1000 does not intend the first and last "pin" structures of the second structural member 1006 to interact with the corresponding head sliders, much like most of the SH actuating pins 1007. , If the pin structure is omitted from the tool, it is still operational for its intended purpose. According to embodiments, each SH actuating pin 1007 exerts a substantially z-direction force (see linear wrapping force 1105 in FIG. 11) in response to actuation (eg, "first actuation"). Apply to the corresponding head slider, thereby wrapping to each target stripe height. According to embodiments, each SH actuating pin 1007 is at the respective target stripe height of the reader element of the read-write head, or at the respective target stripe height of the write device element of the read-write head (also in the figure). It can be actuated to wrap around the "flare point 213") of 2A.

The wrapping tool 1000 has a second structure via or by a third flexible flexure 1014a (“third flexure”) and a fourth flexible flexure 1014b (“fourth flexure”). A third structural member 1010 coupled to the member 1006 is further provided.

In particular, the first flexure 1012a and the second flexure 1012b virtually intersect at a rotation axis around the x-axis associated with the column bar 206, thus defining this rotation axis (see FIG. 11). Represented and explained in more detail). Therefore, depending on the actuation (eg, "second actuation") and based on the virtual intersection of the first flexure 1012a and the second flexure 1012b, each angle actuating pin 1005 has a first flexure 1012a. And around the axis of rotation defined by the virtual intersection of the second flexure 1012b, an angular wrapping force (eg, torque) is applied to its corresponding head slider.

Based on the above-mentioned interaction structure of the wrapping mount tool 1000, an independent and variable stripe height (in the z-axis direction), by activating the stripe height actuating pin 1007, the target of each reader or writer. It can be set on each read-write head of column bar 206 to wrap to a stripe height (sometimes referred to as a "flare point" in the case of a writing device element). Similarly, independent and variable wedge angles (compared to the y-axis direction) by activating the angle actuating pin 1005 and according to the effect of the virtual intersections of the first and second flexors 1012a and 1012b, respectively. It can be set to each head slider (head sliders 208a to 208 m in FIG. 2) of the row bar 206 so as to wrap to the target wedge angle of. In practice, the plurality of angle actuating pins 1005 twist the row bar 206 together in response to actuation and set each head slider of the row bar 206 for parallel wrapping in parallel with its respective target wedge angle. do.

According to the embodiment, the wrapping tool 1000 transmits a pressure gradient in the y direction corresponding to the angular wrapping force (for example, the pressure gradient 904a in FIG. 9A) from each angular actuating pin 1005 to the corresponding head sliders 208a to 208m. Further, the jig 1008 of the first structural member 1002 and a flexible elastomer (such as the elastomer 516 of FIG. 5) bonded to the row bar 206 can be further provided. Therefore, the material removal associated with each head slider 208a-208m by wrapping corresponds to the pressure gradient 904a applied to each head slider 208a-208m.

With respect to the flexible elastomer 516 used to attach / bond the row bars 206 to the angle actuating pin 1005 of the wrapping mount tool 1000, the change in angle from the adjacent angle actuating pin 1005 is that of the elastomer 516 from the angle actuating pin 1005. Separation can be induced, which in turn can induce separation of row bars 206 from elastomer 516 during wrapping. According to the embodiment, the elastomer 516 has a first level surface roughness on the side facing the jig 1008 and a second level surface roughness on the opposite side facing the row bar 206. The surface roughness of the second level is larger than the surface roughness of the first level. Therefore, the effective adhesive force is less for higher surface roughness on the row bar 206 side (ie, by reducing the effective contact area), thereby a more stable row bar 206 removal process (ie, by reducing the effective contact area). For example, the row bars are less likely to be damaged when removed from the elastomer 516 after wrapping). In contrast, the opposing jig 1008 side of the elastomer 516 was made with a relatively smooth level of surface roughness, which maximizes the effective contact area with respect to the mount tool pins 1005, 1007 and is at a relatively high level. Achieve the adhesion of.
Wedge angle flexure of wrapping mount tool

FIG. 11 is a side sectional view illustrating the wrapping tools of FIGS. 10A to 10C according to the embodiment. FIG. 11 is referenced to more detail the operation of the first flexure 1012a and the second flexure 1012b (also see FIG. 7A for similar functionality).

FIG. 11 illustrates a side sectional view of the wrapping tool 1000 and its components according to the embodiments described with reference to FIGS. 10A-10C. FIG. 11 shows that the first flexures 1012a and the second flexures 1012b "virtually" intersect at a rotation axis around the x-axis associated with the column bar 206, thus defining this rotation axis. It illustrates that the first flexures 1012a and the second flexures 1012b that interconnect the rotatable first structural member 1002 and the second structural member 1006 are positioned and configured. An angular wrapping force 1103 is applied to the head slider (eg, 208a-208m in FIG. 2) by 1102 to actuate the corresponding angular actuating pin 1005 around this axis of rotation, and thus the first is centered on it. The structural member 1102 (eg, acting as a lever) and the associated jig 1008 rotate effectively. Recall that the angular wrapping force 1103 (or torque) appears as a pressure gradient 904a (FIG. 9) applied over the corresponding head slider length (y direction) when transmitted through the flexible elastomer 516. Therefore, this independently and variably applied pressure gradient 904a provides WA wrapping control (eg, represented as a block arrow of wrapping force 1103) centered on a common axis of rotation for each head slider. .. The axis of rotation is designed to be at or near or near the center of gravity of the row bar 206 at the wrapping interface / bottom, according to embodiments, so that it is accurate, independent, and dynamically variable. Wedge angle control (ie, by varying actuation 1102 of angle actuating pin 1005) is provided to row bar 206 for each head slider component.

In FIG. 11, a linear wrapping force 1105 (eg, represented as a block arrow of linear force 1105) is applied to a head slider (eg, 208a-208 m in FIG. 2) by activating the stripe height actuating pin 1007. It further illustrates that the stripe height actuating pin 1007 is positioned and configured to be applied. Therefore, accurate, independent, dynamically variable (ie, by varying the actuation 1104 of angle actuating pin 1007) stripe height / flare point control is provided to column bar 206 for each head slider component. Will be done.
Drop impact resistant features

The wrapping mount tool 1000 can be implemented for applications / operations that handle the wrapping mount tool 1000, such as moving between manufacturing sites (eg, by an operator or robotic machine) and, in some cases, different tools. Note that the impact of drop impact / collision on the mount tool 1000 is a consideration and the various actuating pins 1005, 1007 can be relatively thin and fragile components. Thus, referring again to FIG. 11, according to embodiments, one or more functions that serve to limit displacement in order to provide some structural space tolerance between the components of the Wrapping Mount Tool 1000. The clearance control control means can be incorporated into the configuration of the wrapping mount tool 1000. According to the embodiment, the gap 1107 is provided with the terminal portion of the stripe height actuating pin 1007 of the second structural member 1006 and the surface 1106a of the notch 1106 arranged toward the distal side of the first structural member 1002. Provided during. According to embodiments, a gap 1108 is provided between the distal end portion of the second structural member 1006 to which the second flexure 1112b is attached and the opposing proximal surface 1010a of the third structural member 1010. And / or a gap 1109 is provided between the distal end portion of the second structural member 1006 and the opposing proximal surface 1010b of the third structural member 1010. The number of drop impact gaps mounted varies from mount to mount so that any one or more of the gaps 1107, 1108, and 1109 can be mounted to provide drop impact protection to the wrapping mount tool 1000. Can be done. In particular, the multidirectional gap means described above primarily reduces the impact of impact / collision events on the wrapping mount tool 1000 in the z direction (eg, gap 1107) as well as in the y direction (eg, gaps 1108, 1109). Can be done.

Furthermore, at least the combined mass of the main support structure of the first structural member 1002 (including the angle actuating pin 1005), the stripe height actuating pin 1007, and the second structural member 1006 for the stripe height actuating pin 1007. Due in part, the drop test in the y direction tends to induce buckling of the third flexures 1014a and the fourth flexures 1014b that interconnect the second structural member 1006 and the third structural member 1010. Indicated. Therefore, according to the embodiment, the third flexor 1014a and the fourth flexor 1014b effectively reduce the maximum stress applied to the third flexor 1014a and the fourth flexor 1014b in the event of an impact / collision. Implemented as a curved flexure beam (curved along the y direction, as shown in FIG. 11) to prevent or prevent buckling modes of these flexors by causing or mitigating. Can be done. Utilization of such a curved flexure beam can be implemented in combination with the above-mentioned gap means, and can function in conjunction with it.

As discussed, the Wrapping Mount Tool 1000 can be implemented for applications / operations that handle the Wrapping Mount Tool 1000, such as transporting between manufacturing sites and, in some cases, different tools, and thus falls against the Wrapping Mount Tool 1000. Impact / collision effects are a consideration. More specifically, according to embodiments, the wrapping mounting tool 1000 is coupled with one or more structural enclosure interconnects to accommodate the wrapping mounting tool 1000, as well as mounting the mounting tool 1000 with other components, high. Provides a wrapping tool assembly that interconnects with level wrapping tools and / or jigs and is therefore capable of handling and transporting between manufacturing sites and optionally different tools.

According to an embodiment, FIG. 12A is a disassembled top-side perspective view illustrating a portion of the wrapping tool assembly, and FIG. 12B is a top-side perspective view illustrating a portion of the wrapping tool assembly of FIG. 12A. The wrapping tool assembly 1200 includes a wrapping mount tool 1000 articulated or coupled to the assembly base 1202 (“assembly base 1202”). The assembly base 1202 includes a plurality of interlocking pins 1202a (eg, "combs"). Each adjacent interlocking pin 1202a corresponds to a group of adjacent striped height actuating pins 1007 (see dashed circle in FIG. 12B) when engaged with the wrapping mount tool 1000. It is positioned in pocket 1007a. Therefore, the engagement of pin 1202a of assembly base 1202 with the wrapping mount tool 1000 thereby results from the structural configuration and shape of pocket 1007a, primarily in the x direction (represented by arrow 1203 in FIG. 12A). In addition, it also functions to limit the displacement and material stress of the stripe height actuating pin 1007 in the z direction. Thus, the stripe height actuating pin 1007 is generally experiencing a drop impact / collision with a force component in the direction of arrow 1203 and / or when dropping the wrapping tool assembly 1200 in the direction of arrow 1203. In doing so, it can be protected from damage (which can affect the accuracy and performance of the mounting tool).

According to the embodiment, FIG. 13A is an exploded front side perspective view illustrating a part of the wrapping tool assembly, and FIG. 13B is an exploded side perspective view illustrating a part of the wrapping tool assembly of FIG. 13A. The wrapping tool assembly 1300 comprises a wrapping mount tool 1000 articulated or coupled to a mounting plate portion 1302 (“mounting plate 1302”) capable of mounting a PCB according to an embodiment. The mounting plate 1302 comprises a plurality of lower mutual locking pins 1302a (or "lower combs"). Each adjacent lower mutual locking pin 1302a is positioned within the corresponding pocket 1005a associated with a group of adjacent angle actuating pins 1005 when engaged with the wrapping mount tool 1000. According to embodiments, the mounting plate 1302 further comprises a plurality of upper mutual locking pins 1302b (or "upper combs") when each adjacent upper mutual locking pin 1302b engages with the wrapping mount tool 1000. In addition, it is positioned between the components of the corresponding adjacent forks 1003 or a group of forks 1003 to the angle actuating pin 1005. Therefore, the engagement of the lower mutual locking pins 1302a and upper mutual locking pins 1302b of the mounting plate 1302 with the wrapping mount tool 1000 is thereby due to the structural configuration and shape of the pocket 1005a and the corresponding comb of the fork 1003. The displacement and material stress of the angular actuating pin 1005 in the z direction as well as mainly in the x direction (represented by the arrow 1303 in FIG. 12A) resulting from the mutual locking of the upper mutual locking pins 1302a and 1302b having the above. And also to ensure proper alignment with the actuating mechanism when the upper mutual locking pins 1302a and 1302b interact with the corresponding comb of the fork 1003. Thus, the angle actuating pin 1005 is generally when the wrapping tool assembly 1300 is being dropped in the direction of arrow 1303 and / or when experiencing a drop impact / collision with a force component in the direction of arrow 1303. , Can be protected from damage (which can affect the accuracy and performance of the mounting tool).

The lower pin 1302a and / or the upper pin 1302b of the mounting plate 1302 can be mounted independently of the pin 1202a (FIGS. 12A, 12B) of the assembly base 1202 (FIGS. 12A, 12B), but the assembly base. Pin 1202a (FIGS. 12A, 12B) of 1202 (FIGS. 12A, 12B) is mounted in conjunction with the lower pin 1302a and / or the upper pin 1302b of the mounting plate 1302 to angle the actuating pin 1007 and the wrapping mount tool 1000. Note that it can provide protection against drop impact / collision damage to the actuating pin 1005. Also, strengthening the actuating pins 1005, 1007 with the corresponding pins 1302a, 1302b, 1202a can further provide support and protection against damage in the y direction in the event of a drop impact or other collision event. Please also note.
How to Wrap Column Bars on Magnetic Read-Write Head Sliders

FIG. 14 is a flow chart illustrating a method for wrapping the row bars of the head slider according to the embodiment. The various embodiments described with respect to FIG. 14 can each be performed using the Wrapping Mount Tool 1000 (FIGS. 10A-11) described elsewhere herein. For context and as described, each column bar has an x-axis along the direction of the column and a y-axis along the direction of the reader-writer offset associated with the head slider in the column bar. Each head slider comprises a reading device element and a writing device element.

At block 1402, the row bar of the magnetic read-write head slider is secured to the wrapping mount tool jig. For example, the row bar 206 (FIGS. 5, 6, 7A) is the first structural member of the wrapping tool 1000 (FIGS. 10A-11) via an elastomer 516 (FIGS. 5, 6, 7A) and the like. It is fixed to the jig 1008 (FIGS. 10A to 11) of 1002 (FIGS. 10A to 10C) and electrically connected to the PCB mounted on the mounting plate 1302 (FIGS. 13A, 13B).

At block 1404, each of the multiple first actuating pins of the wrapping mount tool is actuated, thereby setting each head slider of the row bar to wrap to its respective target stripe height (stripe height is , Sometimes referred to as the flare point of the writing device element). For example, each stripe height actuating pin 1007 (FIGS. 10A-11) may be actuated (by, as a non-limiting example, pneumatically, hydraulically, mechanically, electrically, etc.) 1104 (FIG. 11). Each head slider 208a-208m (FIG. 2) of the row bar 206 is set to wrap to each target stripe reader height 215 (FIG. 2A), which is a dimension relative to the z-axis direction. The mode in which each respective target stripe height is set is consistent with that described herein with reference to FIGS. 10A-11.

Therefore, at block 1406, each head slider is wrapped simultaneously according to each corresponding target stripe height. For example, according to each linear wrapping force 1105 (FIG. 11), each head slider 208a-208m of the row bar 206 is wrapped according to each corresponding target stripe height 215. It is recalled from FIG. 3 that wrapping can be performed on the head slider or row bar of the head slider using a wrapping jig 304 and a wrapping plate 306 commonly studded with diamonds and / or with a diamond slurry. sea bream.

Continue wedge angle wrapping, if applicable or as desired, to activate each of the multiple second actuating pins of the wrapping mount tool at block 1408, thereby wrapping to their respective target wedge angles. Set each head slider for the column bar. For example, each angle actuating pin 1005 (FIGS. 10A-11) is actuated (by, as a non-limiting example, pneumatically, hydraulically, mechanically, electrically, etc.) 1102 (FIG. 11), y-axis. The head sliders 208a to 208m of the row bar 206 are set so as to wrap around each target wedge angle 303 (FIG. 3), which is an angle with respect to the direction. The mode in which each respective target wedge angle is set is consistent with that described herein with reference to FIGS. 10A-11. Each angle actuating pin 1005 is housed in the first structural member 1002 (FIGS. 10A to 10C) of the wrapping mount tool 1000, and the first structural member 1002 and the second structural member 1006 are mutually exchanged. An angle actuating pin centered on the x-axis, which is a virtual intersection of a first flexure 1012a (FIGS. 10A, 10C, 11) and a second flexure 1012b (FIGS. 10A, 10C, 11) to be connected. A head slider corresponding to an angular wrapping force 1103 (FIG. 11) around the defined axis of rotation through each angle actuating pin 1005, based on a virtual intersection that defines the axis of rotation of 1005 (and thus row bar 206). Recall that it is applied to 208a-208m.

Therefore, at block 1410, each head slider is wrapped simultaneously according to each corresponding target wedge angle. For example, each head slider 208a-208m of the row bar 206 is wrapped according to each corresponding target wedge angle 303. It is recalled from FIG. 3 that wrapping can be performed on the head slider or row bar of the head slider using a wrapping jig 304 and a wrapping plate 306 commonly studded with diamonds and / or with a diamond slurry. sea bream. According to the embodiment, after the first actuating pin is actuated in the block 1404 1104, the second actuating pin is actuated 1102 in the block 1408. However, the order of this operation can vary from implementation to implementation and, therefore, can be reversed if desired.
Wrapping tool assembly with tilted interposer

According to an embodiment, FIG. 15A is a side perspective view illustrating a wrapping tool assembly including a tilted interposer, and FIG. 15B is a side perspective view illustrating a portion of the wrapping tool assembly of FIG. 15A. According to the embodiment, FIG. 16 is a side sectional view of the tilted interposer of FIG. 15A, and FIG. 17 is a side sectional view of the wrapping tool assembly of FIG. 15A. The wrapping tool assembly 1500 includes a wrapping mount tool 1000 (see FIGS. 10A-11) and a plurality of actuators 1510 (in a non-limiting example, air bearing actuators) for activating the angle actuating pins 1005 of the mount tool 1000. , An assembly comprising an actuating interposer 1502 (“interposer 1502”) interposed between the actuator 1510 and the mount tool 1000.

Interposer structure 1502 includes a first element (“interposer pin 1504” or collectively “first element 1504”) that includes a plurality of interposer structures 1504, each of which is reactively coupled with a corresponding actuator 1510. .. Each interposer pin 1504 is configured to receive its translation force 1511 from the corresponding actuator 1510 for transmission or application of the mount tool 1000 to the corresponding angle actuating pin 1005. The interposer 1502 is (a) coupled to the first element 1504 via a first flexure 1505a and a second flexure 1505b, and (b) fixed via a third flexure 1507a and a fourth flexure 1507b. It further comprises a second element, the T-shaped structure 1506 (“T-shaped structure 1506”), which is coupled to the frame or housing 1508. See FIG. 16 for a description of the aforementioned flexure system (flexure not shown in FIG. 15A to maintain clarity) that can be characterized as a zero z-axis (vertical) shift flexure system.

Considering the first element 1504 "suspended" from the T-structure 1506 by the flexible first and second flexors 1505a, 1505b, the first element when actuated in the horizontal (y-axis) direction. The 1504 has a natural tendency to swing or arc upward in the counterclockwise direction, for example, due to bending of the first and second flexors 1505a, 1505b. A simple linear translation of the first element 1504 in the y direction is preferred in order to properly engage and translate the receiving angle actuating pin 1005 of the mount tool 1000 with an actuating force substantially perpendicular to it. Any upward movement (z-axis) of the first element 1504 is undesirable. Therefore, according to the embodiment, the first flexure 1505a, the second flexure 1505b, the third flexure 1507a, and the fourth flexure 1507b are counterclockwise (eg, as shown in FIG. 16). The tendency of the first element to swing upward is configured to be offset by the T-structure 1506 swinging downward in the clockwise direction due to the bending of the third and fourth flexors 1507a, 1507b. As a result, the interposer pin 1504 configured in the first element is allowed or forced to translate substantially linearly only in the y direction.

Referring to FIG. 16, according to an embodiment, the first element 1504 further comprises a z-axis decoupler or separation flexor system from the interposer to the mount tool, and each interposer pin 1504 of the first element of the interposer 1502 , (A) a proximal end 1504a proximal to the actuator 1510, (b) a distal end 1504c including a tip 1504e engageable with the corresponding angle actuating pin 1505 of the mount tool 1000, and (c) proximal. Includes an intermediate structure 1504b between the end 1504a and the distal end 1504c, from which the distal end 1504c extends. The z-axis separation flexure system embodied in the first element 1504 comprises a group of one or more first decoupler flexors 1504f and one or more first decoupler flexors that couple the proximal end 1504a to the intermediate structure 1504b. It further comprises a group of 2 decoupler flexures 1504f. The structural configuration of the first and second decoupler flexors 1504f may vary from implementation to implementation. In a non-limiting example, each of the first and second decoupler flexors 1504f corresponds to each interposer pin 1504 and may include a single flexure 1504f extending from the proximal end 1504a to the intermediate structure 1504b, or , Each may include a monolithic flexor 1504f extending from the proximal end 1504a to the intermediate structure 1504b.

The mounting of the first and second flexures 1504f reduces or relatively reduces the flexural stiffness of this portion of the first element 1504, thereby each distal to the corresponding engagement angle actuating pin 1005 of the mount tool 1000. It allows the end 1504c to follow while substantially separating the effects of forces from each distal end 1504c on the mount tool 1000. The angle actuating pin 1005 and the stripe height actuating pin 1007 of the mount tool 1000 (moving in the z-axis direction for wrapping) are coupled via the first flexures 1012a and the second flexures 1012b of the mount tool 1000 (moving in the z-axis direction). (See, for example, FIGS. 10A, 10C, 11), therefore, recall that the movement of one type of actuating pin can affect the other type of actuating pin. However, in the above-mentioned z-axis coupler decoupler flexure system, the engagement force in the y-axis direction is applied from the interposer pin 1504 to the stripe height actuating pin 1007 (for example, the tip portion 1504e of each interposer pin 1504 is angularly actuated). Acts to be substantially separate (because it engages directly with pin 1005), thereby suppressing or reducing or eliminating such y-axis forces from affecting the z-axis stripe height actuating pin 1007. do.

FIG. 18 is a side perspective view of the pre-aligner of the actuator tilting interposer of FIG. 15A according to the embodiment. With reference to FIGS. 16 and 18, according to embodiments, each interposer pin 1504 is in a position that helps align the corresponding distal end 1504c of the interposer pin 1504 with the corresponding angle actuating pin 1005 of the mount tool 1000. Alignment Bump Structure / Mechanism 1504d (“Alignment Bump 1504d”) is shown to include. The alignment bump 1504d is substantially centered on the corresponding distal end tip 1504e of the interposer pin 1504 in the fork 1003 of the corresponding angle actuating pin 1005 when the interposer pin 1504 engages the angle actuating pin 1005. match.

With reference to FIGS. 15A, 15B, 17 and 18, the wrapping tool assembly 1500 further includes a pre-aligner comb 1512 that positions each interposer pin 1504 within a particular z-axis (vertical) tolerance. That is, the pre-aligner comb 1512 operates so as to restrain the interposer pin 1504 in the z-axis direction. Further, when the interposer pin 1504 properly and securely engages with the corresponding angle actuating pin 1005 of the mount tool 1000, each alignment bump 1504d of the interposer pin 1504 has a pre-aligner comb 1512 and a distal end tip 1504e of the interposer pin 1504. It is positioned between and. Therefore, when each alignment bump 1504d is located outside the pre-aligner comb 1512, each interposer pin 1504 moves freely in the z-axis direction together with the respective engagement angle actuating pin 1005 of the mount tool 1000.
