Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to one-way tape recording technology. More particularly, it relates to digital tape recording technology in which the transformation of magnetic flux generates digital signals for reading and writing to tape. More particularly, the present invention relates to digital tape drives used in streaming or running tape drives, commonly referred to as tape drives.

BACKGROUND OF THE INVENTION Prior art technology for tape drives is directed to various types of tapes. Among these, the present invention relates to a cartridge tape drive used for digital recording.

In recent years, hard disk drives and other recording media have been considered to require backup in the form of tape recorded information. Additionally, certain types of drives are particularly advanced with backup tape recording means in the form of streaming or running tape drives. In addition to these types of computers and related systems,
- Use tape as gaining media. In all of the aforementioned uses, the tape is often loaded with an extended period of time. This delay time is the time required for recording from the middle of the tape to the beginning of star 1. In recent years, the tape has been run continuously in order to make the tape have maximum strength. Many things are being done. This method is known as streaming, in which the tape is continuously run 11 or streamed while reading the already populated Iζ information. The information already written is not accurate,
If the check by the host 1 or controller system does not match, the written information is replaced until it can be read correctly. This feature is employed in streaming in that the tape runs continuously, with no stops and starts for writing, reading, and the accompanying recordings. As a result, the utilization rate of the entire tape is greatly improved, and the tape can be used effectively. This streaming method allows more information to be stored on each tape than with the prior art.

The present invention relates to a unique tape drive that is related to, but distinct from, streaming. The streaming tape drive disclosed in U.S. Pat. No. 4,414,593 uses a standard 4 x 6 inch (101,6 x 152.4 mm) tape car 1-ridge.

A 4 x 6 inch tape cartridge is inserted into the tape drive with the 6 inch width across the front of the tape drive. The platform into which the tape cartridge is inserted is generally a module having an outer diameter of 8 inches (203,2 mm>).

In recent years, it has been considered that backup and original recording tapes should be used in conjunction with current small disks, on the order of 5'/inch (133,4 mm). There are 4 tape cartridges to be manufactured.
x6 inches in size, it can only be used with the present invention in smaller standard size systems.

The present invention is a wide dot tape cartridge for the purpose of inserting a cartridge having a widthwise section of 6 inches standard size into a narrower standard size section, that is, a tape cartridge inserted over a 4 inch width. are doing.

ANSTX=37-3.55-1982 for unrecorded tape cartridges for information processing defined by the American National Standards Institute (ANSI) defines tape standards.

According to this, the tape must be oriented in a particular direction. This type of tape is required to have three planar cartridge positioning surfaces along the top surface of the metal back of the tape cartridge. Such a plane is called a 1B plane. The 6-inch portion of the cartridge from which the tape is exposed for recording and reading is referred to as the "A-plane." Regarding the aforementioned mounting position, the American National Standards Institute requires tape cartridges to be mounted in a read-write device only in a single position, and to prevent improper mounting. It is considered to be symmetrical.

According to Figure 5 of ANSIX3.55-1982, 4×
The loading direction for the 6 inch cartridge is shown as being from the 6 inch dimension of tape extension. The present invention eliminates the need to use 6 inch sized sections and allows smaller standard dimensions to be used. The device is unique in that the device for using the same tape is an entirely different system rather than reloading the tape. The device uses specific tapes defined by the American National Standards Institute for completely different types of tape. This is one of the features of the present invention. The present invention involves a frame into which a tape cartridge can be inserted through a panel into a Freon 1 equipped with an electrostatic discharge section. When inserting the tape, the tape is moved against an ejector arm with a brake mechanism. Braking IJI
A side-mounted ejector arm controls the speed of cartridge ejection from the drive. When a tape cartridge is inserted, the cartridge door is cammed open by a cam having a curved arcuate surface. The cartridge is then held precisely in place by rollers that engage locating surfaces on the cartridge.

The cartridge 1-ridge is held as follows by movement of the knob. The lever is the car 1 heritage base play 1-
J] and at the same time move the roller with spring force so as to engage the notch on the base plate.

This holds the cartridge in the aforementioned A-plane, and at the same time holds the cartridge upwardly on the three points of the B-plane of the drive mechanism.

In addition, by moving the knob, the erase section can be erased or erased.
~The head protrudes and is brought into contact with the tape. The head is moved relative to the track in an azimuth or rotation about a vertical axis, a rotation about a zenithal axis (i.e. a rotation about a horizontal axis, and a constant plane position). The track is adjusted to provide such positioning. When moving to the tape, the head is cushioned and stopped by a plurality of leaf springs. The leaf springs are adjusted to provide proper tape contact spring damping. The entire movement is performed by a linkage. The linkage includes a pivot point for overcenter action that is biased in part by an overcenter spring.

As mentioned above, a standard profile tape cartridge based on ANS I is housed in a cartridge tape drive in a narrow area, and the head moves relative to the tape cartridge whose door is automatically opened upon insertion. Contact. Movement of the tape head into rotation about the vertical axis and rotation about the horizontal axis is effected by four spring arms. The spring arms guide the tape head upwardly and downwardly in parallel to prevent the tape from being oriented angularly (eg, horizontally). All of these features are provided for improved loading and tape cartridge orientation.

In short, the present invention is equipped with a cartridge locking system operated by a knob on the front panel 1, which is equipped with an ejector with a cartridge braking mechanism, and further includes:
It involves movement and orientation of the head, such as rotation about a horizontal axis, rotation about a vertical axis, and other orientations relative to the cartridge.

The details are as follows. The present invention provides a cartridge tape with a hole in the front panel for receiving a cartridge.

The front panel has a plastic type electrostatic discharge section on the front side. The discharge section has electrical conductivity to a certain area of the frame, thereby discharging or washing away the amount of charge of the operator or other charged object that comes into contact with the front panel. - The panel also has a conductive f!
1]-ting is applied, which makes the drive J
Rex 1-0x is shielded from electromagnetic interference. The drive of the present invention further includes a highly conductive tab that grounds the base of the cartridge. During cartridge insertion, the cartridge is stopped at J3 at the end of insertion by an abutment and oriented by a knob. The knob includes a lever and a roller coupled to the lever to lock the cartridge in position and to attach the cartridge to the rear of the drive.

The drive of the present invention is characterized by a movable write and erase head. That is, the head moves to contact the media of the cartridge after the cartridge door is opened by a unique cam and drive curve for opening the door upon cartridge insertion.

The read-write erase head is moved upwardly and downwardly by a stepper motor. The stepping motor moves the head in the proper orientation with an arm supported by four springs and accompanying the orientation of the head in the proper mode.

A read-write erase head engages the tape as it moves over the track. The track is easily adjusted by two directional adjustments: rotation about a horizontal axis and rotation about a vertical axis relative to the tape and cartridge with which the track is to be opposed.

The cartridge is driven by a capstan that is belt driven by a motor. The motor is controlled by a controller board and an associated host.

Relief and movement of the cartridge from the tape drive is accomplished by a knob. The knob is read-write.
Without moving the erasing head out of the cartridge, the cartridges are both released from the positions marked in each direction on the A plane and the B plane. Upon release, the cartridge is lifted over the shelf by a cam surface that abuts the lifting tab. As the cartridge passes over the shelf, the ejector arm with an insertion brake is able to gently move the cartridge and eject it out of the tape drive opening.

Movement of the read-write head with proper orientation on the track is facilitated by an overcenter spring. The overcenter spring causes the read-write-erase head to take an overcenter action to reach two mode positions, respectively. Thereby, locking of the head can take place in two positions, each in a spring-loaded manner.

Detection of the proper position of the cartridge within the cartridge drive system is accomplished by switches, light emitting diodes, and optical sensors when the cartridge is in the proper position and the start and end portions of the tape are functional.

Optical sensors and light emitting diodes can be controlled to each slide in position relative to the cartridge, thereby detecting and reading beginning and ending portions of tape as well as other tape movement.

The various elements described above are used to read and write to maximize the use of streaming cartridges.
Combined to form a superior tape cartridge drive with erasure capabilities. The cartridge drive has the advantage of lateral insertion in that standard sized cartridges can be inserted with the narrow section rather than the wide section. The cartridge drive allows the use of computer memory devices with modern dimensions and can use standard cartridges with a 4 x 6 inch profile, typically used in the 8 inch standard mode.

Embodiments Hereinafter, the present invention will be explained based on embodiments shown in the accompanying drawings.

If one looks particularly closely at FIG. 1, it will be seen that a perspective view of the present invention is shown in the form of a cartridge tape drive frame or basic mechanical assembly rt of the present invention, designated generally by the numeral (10). Below the frame or cartridge tape drive (10) is the controller chassis (12).

The controller chassis (12) can be generally integrated in the same configuration, or can have leads from associated equipment to the frame (10) that are separated by a particular frame (10) arrangement.

In this special mode, frame (10) is
It is a Le style form, and 5! It is adapted for placement on small magnetic media and other disk drives in the /4 inch range.

The frame (10) that is the subject of the present invention will be explained excluding the controller chassis (12).

In juxtaposition to 4) there is a movable knob (16) or lever and a fixed knob (18). This movable knob or lever (16) is specifically for actuating and securing the cartridge in position and for removing the cartridge in the manner described below. The purpose of the fixed knob (18) is to provide a thumb grip for moving the movable knob or lever (16).

Figure 3 shows the cartridge insertion or frame (10)
Figure 9 shows the cartridge in position.

As can be seen in particular from Figure 3, the cartridge (20) is placed in the frame (10).

The cartridge is received through the opening (14) and the panel (19) in the direction of the arrow (22). To move the cartridge in the other direction and take it out, lift it outward from the frame (10) using the method described below.

Insert the cartridge (20) into the opening (14) of the panel (19).
), static charges are often generated on the operator, cartridge or other associated items. In order to discharge this charge, the panel (19
) is made of conductive plastic (19a). The plastic is also a relatively high resistance material. Such plastics are known to have graphite therein or other conductive materials. The conductivity of this material can be sufficiently high that the magnitude of the current due to the discharge, and thus of the electrostatic field produced thereby, can be controlled.

Figure 20 shows the material form of the panel (19).

The back side of the panel (19) is plated with plating (19b) and connected to ground to discharge the charge from the panel (19). Therefore, the electric charge associated with the insertion and removal of the cartridge 1-ridge (20) is
9a) and is discharged to ground via the conductive plated surface on the back side.

The plated surface (19b) also acts as an electromagnetic interference (EMT) shield for the drive electronics. Therefore, electrostatic forces are discharged through the panel material (19a),
EMT forces are also shielded through the conductive coating (19b). A leaf spring (23) secured by two screws contacts the cartridge (20) so as to discharge the static charge when it is inserted.

When the cartridge (20) moves inward, the opening part (1

There is a metal plate (34) at the bottom of the cartridge (20),
This is shown in its general shape housed in the opening (14) and is shown in Figures 4(a) and 4(b). The metal plate (34) at the base of the cartridge is a standard metal plate and has what is commonly referred to as an alignment ledge (35) with an internal surface (38). (35) serves to align the entire cartridge with respect to what is known as the A-plane or A-plane as set by the aforementioned ANSI (f.).To further explain, the A-plane is shown in Figure 4A. Like, JJ-1
~Located at the side edge of the ridge. This end is indicated by the ends (40) and (42) at each end of the cartridge, and is indicated by the line (A)--
It touches the △ plane shown in (A).

The A-plane for the cartridge is shown in Figures 6.8.12 and 1.
It is generally defined as the flat part that extends to the left side of the Kerr 1 edge, indicated by 3.

This surface in the A plane () is the surface of the Kerr 1 heritage (
40) and (42), and as part of the other cartridge (44) shown in FIGS. 4A, 4B, 9 and 3. These two surfaces (40) and (42) comply with the aforementioned NSI standard, namely the ANS published by the Amerino J Standards Association for information processing of unrecorded magnetic tape cartridges.
Provides a plane relationship based on the ANS II standard corresponding to IX3.55-1982.

The B plane or B plane set by the aforementioned standard is:
It is defined by three points on the top or inside surface of the bottom or metal plate (34). The first point is Fig. 3
It is set at point 46 on the portion of the cartridge pointing upwardly towards the front end as shown in FIG. This point (46) is also shown in FIGS. 12 and 13. The second point is

The third point defining the stabilizing B-plane of the cartridge plate (34) is the point (50) shown in FIGS. 3 and 4A, which is located approximately at the midpoint of the cartridge plate (34). ) at the top.

Therefore, points (46), (48) and (50) are

In effect, the ejection arm (52) locks the cartridge in place within the tape drive by pushing the cartridge against the inner surface of the ledge (24).

Looking specifically at the cartridge (20), it has two tape spools or reels, just like any other cartridge. 1-1 A straw tape (60) runs between the spool (56) and (5th). belt key 1
A seven push stamp (64) is shown which drives the spool (56) through the bell 1 to guide roller (66). The shaft or spool (56) is the supply hub, while the shaft (58) is the take-up hub.

The tape is moved back and forth so that the oxide portion of the tape is exposed to the outside at the read-out head window as described below.

The tape cartridge cartridge (20) inserted as shown in FIG. . The door (70) is shown in Figure 5B? l

) is heard. The rotational action to place the door (70) in the open position is provided by an elongated block (82) shown in detail in FIG.
) is effected by the action of a drive surface (74) that engages with a first cam surface (80) formed in an arcuate shape. The arcuate cam surface (80) functions to rotate the door (70) to pivot 1 about point (72) as shown in the direction of travel of arrow (76). After the final insertion, the door assumes the fully open configuration as shown in FIG. 'rJ
That is, the drive surface (74) or the protrusion (74) is
Pushed around the arcuate face (80), the door (1o) is brought to the open position.

When inserting the cartridge (20), it must be properly aligned with respect to the A-plane setting, as described above with respect to point (42). This is adjusted by the h method seen in FIGS. 4A and 4B. There, the A-plane surface (42)
is first moved against an inclined centering surface (9o) = 56 - formed by part of the block (82). The lower centering surface (90) of block (82) is aligned with the inner surface (90) of block (82).
Move the A-plane surface (42) into close proximity with 2). As it moves inward, it is engaged and secured in place by the inner surface (38) of the A-plane setting ledge (36) which engages the roller (94). This roller is spring loaded so that it can be driven against the internal surface (38) to hold it in place.

As shown in FIG. 111B and FIG. 4B, the roller (94) has a spring portion U (98
) It is designed to rotate based on its spring force. This causes the rollers to closely engage the plate (34) against the inner surface (92) and A
This ensures contact of the point (42) with the plane. Car 1-
Another part of the A plane that is located in front of the ridge, namely the point (
4o) is set as described below by the operation of a movable knob and its attached rollers and levers.

As can be seen from the foregoing description, the tape (20) is inserted into the door so that the read and write heads configured below can move into engagement and penetration of the tape for the functions described herein. There is. However, before performing the functions of the read-write-erase head, and before the interlocking movement that occurs concurrently with the insertion described above, other portions of the A-plane must be set up.

To secure the Car 1 ridge to the rest of the A plane, the Car 1 ridge plate (34) can be seen resting on the frame sill (26) behind the ledge (24). As the movable knob (16) shown in FIG. 7 moves to the right, the slide lever member (104) having an extension (105) connected to the movable knob moves to the right, thereby causing the movable knob (16) to move to the right as shown in FIG. Engagement of the cartridge plate (34) occurs. FIG. 8 shows the settings of the plane surfaces of plane A and plane B. In particular, it shows the six-plane surface (40) of the plate (34) and the adjacent B-plane surface zone (46). Slot 1~ or the opening to the right of the ledge (110) is
An internal surface (112) similar to internal surface (38) is shown in FIG. The spring member (116) connected to the first part of the slide lever (104) and the spring biasing part (1)
It is this inner surface that is engaged by the roller (11/I), which is connected to 1B>.

The slide lever (104) has a knob (120) extending outwardly from the chamfered surface (122), which allows the ledge (110) to rest on the inner surface (124) shown in FIG. Useful for Laura (114)
serves to move the cartridge plate (3/l) upwards by the spring force of the rollers. The roller (1111) has a knob (831J) on the front of the drive that is the checking part for the B plane.
For the lower part of 124), press 46) or 8 reference plane. At the front of the board (Pull B plane verification section has a knob (
104) is set for the 15 surface (124). The A-plane is also set by a roller (114) that offsets the ledge at the Δ-plane point (40) relative to the aluminum block (125) shown in FIG. 6 (40) at the front of the cartridge.

The foregoing action serves to establish the B-plane point (46) and is held against movement by the fixed engagement of the roller (114,) with the inner surface (124>) of the knob (120).

The foregoing serves to establish the interrelationship of the two points in the A and B planes while simultaneously holding the cartridge (20) in place. A lever assembly is attached to the sliding knob (16) to provide spring horns and support.
Mounted on two rods (130) and (132).

These two rods (130) and (132) move the slide lever (10-60-4) back and forth.1. It is useful for r. The slide lever (104) shall include an entire block supporting the knob (120) and other elements shown in FIG.

to prevent or close cartridge insertion.

The slide lever (104) fixes and holds the cartridge (20) in a predetermined position, and also biases the slide toward the A plane and B plane at the front, that is, the A plane portion (40) and the B plane portion (46). It provides multiple functions.

B-plane section (46) and B-plane section (25) placed on the plate (34) below the ledge (36) or extension
Co-operating with is a third B-plane support which is a spring-loaded ball (150). This spring biased ball (150
) is a block (82) having an opening (152) through which the ball (150) is installed;
inserted through. The ball is spring-loaded by a spring (153) with a back-up insert at the rear for fixation within the block (82).

The aforementioned ball (150) has three points set in addition to the aforementioned two points on the B plane. This holds the cartridge in a precise position for compatible read-write functions. Looking specifically at the block (82), the block includes the aforementioned arcuate cam portion (8o) and centering portion (92), and the range (154) extending from the block with the undercut (156) below. You can see that they are placed together. The range (154) has a plate at the rear of the cartridge (
34) is formed below it, forming a part that can be inserted under the Zunawa no 5 space (156). At the same time, the lower part of the cartridge and the J-angle surface (1

In effect, the spring ball (150) hits the board (3/I) against the space (156) of the ledge (154) below the board (3/I).
37I) and press the last point (
50).

It can be seen from the foregoing that since the A-plane and B-plane requirements are established by the respective support arrangements, proper alignment of the entire cartridge can be achieved. For proper read-write and erase functions, the head is maintained at the proper azimuthal angle, ie, rotation about the vertical axis, and zenith angle, ie, rotation about the horizontal axis, relative to the tape. The Kerr 1 heirloom (20) is maintained in proper A and B configuration by the present invention providing head azimuth and zenith angle adjustments. Thus, once the tape is in place, its proper placement is maintained at all times by the head, which is adjusted to align the cartridge with its set A-plane and B-plane.

As with the previous one, the A-plane and the 8-plane are configured with respect to the aforementioned actuation and movement of the mechanism to hold the cartridge in place. Once the cartridge is in place and set in the A-plane and 8-plane mode relationships, the head moves to the tape positioning and piercing position. This is accomplished by the movement of the movable knob (16) by means of a linkage, which will be described in detail later.

In particular, FIGS. 10 and 11 and the slide lever (104
The linkage shown in FIGS. 3 and 9 together with the diagrams illustrating the operation and operation of the read/write head described below will be explained in more detail.

A read-write head assembly (170) is shown in FIG. The read-write head assembly (170) has a read-write head (172) thereon, which consists of a reading section and a writing section. This head includes, in particular, a magnetic section (173) with an erasing head section (174), a reading section (176) and a writing section (
178). This is attached to a support plate (179). The respective read, write and head parts are shown in Figure 1.
0 and in the plan view shown in FIG. Furthermore, the read, write 1~ and erase heads are based on the above-mentioned ANS.
A conventional read-write/erase head is shown using T, which is commonly used with most tapes.

A read-write head assembly (170) with support plate (179) is supported by two screws (180) and (182) connected to a block (184).

The block (184) is then supported by screws (180) and (182) passing through the support plate (179) and downward through the block which are connected to four equally spaced spring cages.

The two lower spring members (186) and (18B) are attached to the spacer block (1) located at the negative part of the lower block (194).
92) is connected to the second block located at -H.

The aforementioned items are screws (196) and (19B) respectively.
is maintained by Screws (196) and (198) pass through (192) and (194) of the lower block portion to hold the entire assembly together, and are also shown respectively in FIG. 15 and in the exploded assembly of FIG. It is intended to hold the two lower spring members (202) and (204) shown in the figure.

Spring members (186), (188), (202) and (2
04) has low stiffness in the vertical deflection mode, but very low stiffness in torsion (azimuth), lateral translation (head position), and inward translation (head penetration). In other words, the spring member allows for translational movement of the head across the front of the tape, but the rigidity of the rotation due to the distance M from the vl axis in the spring member changes these to the azimuthal relationship and the head position. Can be held accurately.

The above-mentioned t) are all fixed to the movable plate (210>, and this movable plate moves back and forth by the link mechanism of the present invention to operate as shown in FIG.
70), and allows for proper movement and adjustment of the stepper motor (212) without moving the head up and down across the front of the tape.

Next, looking at Figure 15, there is a nut (21 = 1) internally connected to the stepper motor (212), which rotates to move the drive screw (216) and has the effect of moving it up and down. There is a stepper (212).

This movement causes the head support plate (170) to extend from the block (174) to the reblock (1).
7/l), this head support plate rises. The extension (220> has a square or rectangular interior (224) in which the screw (
216) is threaded through and secured to the spring washer (226) which secures the screw (216) in place.

Therefore, as the head support plate moves up and down, the plate, washer or other member fixed to the shaft, such as the plate (230
) can be moved up and down. In this way, the extension part (220) can move up and down, and the extension part (220) can move the block (17/l) to which the head assembly part (172) is connected for up and down movement in a blocking manner. Become.

A unique feature of the present invention is that the stepper motor (212
) actually rotates the nut (214) rather than the screw (216). In fact, the screw (216) remains stationary with respect to its rotation and the nut (216)
4) only moves in its longitudinal direction as it rotates with the motor (212).

It is possible to rotate and lower the oak h (214) to the 10th teaching point.
6) Move downward to the U point where both can be repeated. When Nara 1- (214) rotates, the screw moves downward and hits stopper (238>).
This is the starting point for the roller disk and the hoss unit, which allows the head (172) to be started from a zero index point and to move the head (172) across the plane of the tape to provide various channels of movement. I'll have to move it.

The tape track moves in a tortuous manner back and forth across the front surface of the head (172) due to the up and down movement of the head relative to the tape. As the tape moves back and forth, the lead-
The layout of the lie I head is as follows.

The overall relationship of the head across the front surface of the tape and the curvature of the tape allows a plurality of channels, such as 9.14 or more channels, to be established across the front surface of the tape.

Spring members (186), (188) and (202)
0/l') is dimensioned so that the screw (216) moves up and down, and the head (172) remains aligned in its azimuth with respect to the tape.

In fact, arms (202), (204), (186), (
188) allows for controlled movement, so the azimuth does not deviate.

For purposes of discussion, azimuth with respect to computer arp drives will refer to the angular displacement of the head from the tape. Azimuth, if present, is 900 degrees from the direction of tape travel or an offset from the vertical. In other words, it is a plane or line that describes the placement of the read-write head elements at the most preferred 90 DEG from the tape line of travel.

Maintaining azimuth is very important. Because lead-
This is because if the lie 1~head is tilted with respect to the tape, or angularly tilted 1"12i, this will of course increase the overall space required for writing on the tape. This will cause the reverse flux to overlap or , or cause the peak not to be exactly at the optimum point for the maximum flux density.Of course, flux density is not the only factor for recording. Importantly, one reverse flux does not overlap or distribute itself with respect to other adjacent reverse flux areas.

Therefore, the angle or azimuth of the beam head with respect to the direction of travel is of paramount importance. This arrangement should be kept close to (J vertical (') O'). That is the normal state of azimuth, which should be maintained, and the springs (186), (188) and (202) and (204) are of the same length.
) is realized.

Another point of particular interest is whether the head tilts inwardly or outwardly across the front of the tape. In other words, the read-write portion of the head must be in sufficient contact with the tape across its width. Otherwise, some parts of the tape will have less contact while other parts will have more contact. This is technically called the zenith angle, and will be referred to as such below. It is important to maintain this major apex angle as well, and this is improved to some extent by the placement of the support plate (210) which helps to adjust the azimuthal angle as well as the major apex angle to keep it in place.

The support plate (210) shown in Figure 10 moves back and forth and is supported by adjustment screws or screw assemblies (254> and (256)) and is located in a track (252) J2 located in the track (252). 252) is the frame area (258

58) receives a track (252) in its -V and is adjusted by the use of a screw or screw assembly screwed into the frame, which is shown in detail in FIG.

Figure 18 shows the arrangement of the tracks (252). Tracks (252) are screwed into the frame for adjustable placement by screw assemblies (256) identical to screws (254). This allows the screw assembly (256> with a hexagonal head screw (264>) to be threaded into the thread (266) formed in the boss (267) of the track (252).

This hexagonal head screw (264>) is connected to the frame part (258

) sets the position of the track (252) in the frame (258), the fixing screw (27) with head (276)
4) fixes the vertically moving screw (264>) at the set position.The head (276) is spring biased to hold the fixing screw (274) for fixing the adjusting screw (264). It is adapted to engage a split washer (278).

The aforementioned two screws (264> and (274) are located in the screw adjustment assemblies (25/I) and (256) and are located in the track (
252) can be moved up and down with two points where adjustment screws or screw assemblies (254) and (256) are located.

The movable plate (2, 10) is shown in Fig. 10. Moves back and forth on the track (252) as shown in FIGS. 11 and 19.

The clip spring part (290) is biased by J: 1 = spring (

The roller (286) operates in conjunction with the roller (284) which is carried by a plate (216) on top of the roller (284), both of which engage tightly with the track (252) in a gripping manner. However, since rollers (282) and (286) are both free to move in their rotational relationship, plate (210> moves on rack (252) to 1. Therefore, plate <210> moves according to the arrow in FIG. It is moved back and forth in the direction of.

This allows you to freely arrange the track (252>),
]・Due to the arrangement of the rack (252), the plate (21
0) will move above it.

Therefore, as the i-rack (252) blocks down -L, the plate (210) moves. The plate (210) is connected to the arm (
186) do (188) OJ: and tape, (202) and (
20/I) read-write head ('172)
Insofar as it is connected to the supporting block (190), any movement or adjustment of the rack (252) will be transmitted thereto.

Movement of the head in terms of azimuth and zenith angles is achieved by rivets or pins (294) on plate (210) frame section IIi.
! (298) is achieved by interlocking facts. However, this engagement is made with plate (210) free to rotate about pin (294). The frame area (29B) supports the plate (210) with pins in a very tight manner in movement. The pin (294> is the plate (
210) downwardly into the frame area (298), a pin fixed to the plate may apply a constant force to the pin. This can be achieved by a spring or snap washer on the rear of the pin (294,).

That is, the head of the pin (294) is connected to the frame section [(
This is because it is tightly held against the plate (210) which is hingedly held at the plate (298). This provides a pivot point around pin (294).

From the positioning described above, the plate (210) has the pin (294>
It can be seen that it is attached by and has a fixed arrangement with respect to that area. Therefore, if the read-write head assembly (170) needs to be tilted with the tape adjustment screw assembly (256) for positioning, the azimuth will be adjusted. This is because the head is tilted angularly across the plane of the tape with respect to the direction of tape travel, and this tilt modifies the azimuthal angle.

This is shown in FIG. That is, the head (17
2) engages the tape and if tilted between the points set by pin (294) and screw assembly (256);
The head will correct the azimuth.

The zenith angle can be corrected by a screw assembly (254) that moves the head to tilt the head inward and outward across the tape plane.

Thus, as shown, the positioning of the tape in terms of azimuth and zenith angle is achieved by two screw adjustment means or assemblies (254) serving to respectively adjust the zenith angle and azimuth angle of the head assembly (170). ) and (256).

The foregoing allows the head (172) to be adjusted to the correct A-plane and 8-plane for tape or the like. If there is a misalignment of the head with respect to the A plane and B plane of the tape cartridge when the tape is stored, it can be corrected. This is important insofar as flux density and overlap are constant issues with magnetic media, and accurate alignment must be maintained and maintained for reliable data exchange from drive to drive.

Once the head assembly (170) is properly positioned with respect to the tape, the entire tape is
) can run freely across the head for any particular track. This is due to the following fact. In other words, regardless of the vertical movement of the head on the spring worm, the arm (1
86), (188), (202), and (204) hold the head so that constant azimuth and zenith angles are maintained.

When the car 1-ridge moves into the opening of the frame, i.e. the opening (14) shown in FIG.
6> and engages with a spring member (300) acting above the shelf (30) and biasing it upward. This upward biasing spring member (300) forces the rear portion of the cartridge into a planar area (302) of the blocking member (82).
) Lift it up to the point where it slides all the way up. The j-tridge is then forced upwardly so that its plate (34) is received on the inner surface of the ledge (154) of the undercut (156). This is accomplished by a spring-loaded ball (150) pushing the plate (34) in place against the ledge. Therefore, point (50) on the B plane shown in FIG. 4A
and point (48) are set appropriately. The 8-plane points (48) and (50) of the cartridge are registered in a negative orientation relative to the 8-plane reference of the block so as to provide the final proper alignment.

As mentioned above, the damper ejector arm (52) serves to cushion the storage of the cartridge (20) as it moves inside. Arm (52) is shown in the retracted position in Figure 9, where cartridge (20) has been inserted. The arms (52) are also shown in FIG. 3 in a retracted or outwardly moving position.

The damped ejector arm (52) of Figure 16 incorporates a dependent bin (308) that engages the end of the cartridge (20) when inserted. Arm (52) and bottle (3
08) is positioned to be driven back and forth by a spring (312). As you can see, the spring (312)
is holding down the flange (314) of the arm (52).

Said details are shown in figure (16) where the spring (31
2) is shown engaging the fixed pin (318) at one end in one case and a portion (322) of the side wall (320) of the frame in the other case. This side wall portion (322) has a spring (312) at that point (324).

High viscosity silicone grease (346) and (348) is contained within the interface area at the ends of peripheral walls (336) and (332). This grease helps to bond and at the same time provide sufficient lubrication so that the spring (312)
52) will not suddenly snap when moving back and forth.

Referring to FIG. 2, the side wall (320) of the frame is screwed into the frame at a threaded hole (360) that receives a screw passing over the threaded hole (362) in the frame member (320). : The hook (364) is latched to the second hook (366) on the front panel.

The sacrum portion of the wall (320) is secured by screws passing down through the frontage (368) and up to the threaded holes (370) in the frame. To drive the capstan (64) into the cartridge (20), drive wheel set v1
The drive wheel unit (380) is utilized. The drive wheel assembly (380) is essentially shown in FIG.

Drive wheel assembly (380) incorporates a pulley (382) driven by a belt (384). belt(
384) rotates the spool (382), causing the elastomer drive wheel (386) connected thereto to rotate. This J-rath 1-mar drive wheel (386) meshes with the carburetor methane (64) to rotate the respective reels (56) and (58).

The drive wheel (386) is supported on a shaft or spindle (392) mounted IJ in brackets 1-(388) to the right of the opening shown in FIG.

In particular, the brackets 1 to (388) have a frontage (390), and the frontage (390) receives the support shaft (392) or the main shaft. The main shaft (392) has brackets 1 to (38

The entire bracket (388) consists of two hinged arms (
406> and rotate inward and outward on (408). The hinge arms (406) and (40B) have a coil spring (410) between them, and move back and forth to connect the main axis (392) of the bracket 1 (388) to the plate (Figs. 10 and 11).
surface (416) of opening (417) shown above
). The surface 116) has a main axis (392
) provides a driving action to the spring-loaded bracket (388) and the main shaft (392) as it moves back and forth relative to the surface (416). Thus, when the head assembly is in the retraction phase, the main shaft (392) moves into the rounded opening (420) in the surface (416). This is held there until the plate (210) moves forward for engagement by the tape read-write head. At times like this, the main axis (392)
begins across surface (416) and remains there until forced rearward by side pressure of cartridge capstan (64) acting against the pressure of spring (410). This causes the drive roller (386) to be placed tightly against the capstan (64) in the manner shown in FIG.

FIG. 10 shows a drive wheel assembly (380) with a drive wheel (386) in which the cartridge (20) has an opening (4,16) having surfaces (4,16).
/117), forcing the drive wheel to be located near the rear of the vehicle.

To ensure that the arms (406) and (408) engage with the frame, the bin (430) passes through the arms (406) and (408) into the frame 11 portion (432) and as shown in FIG. It enters the upper frame portion (434) which forms part of the block (436).

Therefore, the drive wheel assembly (380) is held in its entirety by arms (406) and (408) that limit the back and forth movement of the entire assembly (380) by the spring force of the spring (410). . This spring is driven [1-ra (38

) is braked by a plurality of leaf springs (466) connected by. The screw (467) is connected at one end to the spring (466), allowing the spring to deflect at the other end. The leaf spring (466) brings the plate (210), which is driven by the spring (=166), into contact with the soft spring plate (210).
468) or the protrusion is engaged and cushioned by a spring (466) to prevent undesired shocks to the read-write head.

The spring (466) positively stops the protrusion in position to prevent the U1 read-write head (172) from contacting the tape by more or less than the required amount. If this is not done, the magnetic This creates unfair publicity in the media.

Adjustment of the leaf spring 1 to collar assembly consisting of the leaf spring (466) can be performed by means of the spring support brackets 1 to (470>) which are movable by loosening the two screws (/172) and (474). The bracket 1-(470) rotates around the screw (47/I), and the screw (472) passes through the shackle (473) so that its adjustment can be performed. The spring (4166) can be moved toward or away from the protrusion (468) by deflecting the pin (476) inward and outward from the connection point of the spring. : The pin (476) or the collar protruding upward from the brackets 1 to (470) is connected to the leaf spring (
7166) close to the protrusion (468).
You can move it so that it doesn't move away from you.

Therefore, the point of impact of the protrusion (46B) of the plate (210>) can be adjusted by the pin (476) which pulls or loosens the leaf spring (466) to some extent by tightening or loosening the screws (472) and (474), respectively. is damped by a spring (466) which is moved by the
Adjustment of the entire spring engagement part can be performed. The spring engaging portion includes a leaf spring (466), which is connected to the leaf (210).

The laterally moving plate (210) is moved for outward and inward movement by a mechanism in the manner described below. As shown, the plate (210) is moved relative to a movable knob (16) that slides back and forth across the plane of the cartridge frame.

To remove the tape cartridge from the frame, the movable knob (16) is moved to the left position as shown in FIGS. 12 and 13. As long as the movable knob (16) is connected to the slide lever block (104), the knob (16)
) moves the parts it connects. As shown in the figure, the slide lever block (104) has a rod (130) and a slide lever block (130).

It is attached to the block (104) by means of rivets 1 or other suitable attachment means. This also includes an upright plate (48) connected to the slide lever block (104).
6), this plate slides as the enabling knob (16) moves from side to side. In this particular case, this knob is slid to the left for cartridge removal. Due to this action, the arm ([34)] lifts the cartridge,
It can be taken out using the method described later.

As shown, the arm (484) is stepped and has a downwardly projecting surface (492) that acts as a cam member.
) ends at the right end (490). This cam portion $,1 (492) has a cam surface (
498) is suspended.

This is shown in detail in Figure 8, where block (496

Suspended on a spring arm (500).

The spring arm (500) pushes the block (496) over the frame base provided by the shelf (26).
By lifting it in the V direction, it can be bent up and down as shown in FIG. Therefore, the cartridge (2
0) is lifted above the shelf (26) and over the lip (24) so that the cartridge can move over it.

Movement occurs when the block (496) is suspended from the bottom of the cartridge and the ejector arm (496) is suspended from the bottom of the cartridge.
The spring force of the cartridge (20) in the opening (14)

Therefore, the foregoing eliminates the ejecting function of the cartridge (20), and also the link function attached to the plate (210) pushes the read-write head assembly (170) backward through the movement of the knob (16) to release the tape. disengage with. Additionally, the tape cartridge door (70) is spring biased, so that the door closes after disengagement from the rounded arcuate surface (70), which preloads the door.

The ANS I standard for tapes specifies a small spring at the pivot point (76) of the door (7o). The spring serves to close the door and place the tape on top.

In the mechanism shown in Figures 10 and 11, a movable knob (16) is connected to a block (1071) allowing movement thereon and sliding on support rods (130) and (132).

As the knob slides from left to right as shown in FIGS. 11 and 10, it serves to engage the magnetic head assembly (170) with the tape in the manner described above. This is accomplished by means of a sliding arm (484) connected to the frame with a pin, rivet or bolt (600) as shown in FIG.

The pin, rivet or bolt (600) is provided so that the arm (484) can slide back and forth in the slot (602).

As can be seen from the movement of the slide arm (484), movement to the right is indexed and accomplished by movement on the bin (600). This bin has slots (6

In order to increase this indexing movement, the protrusion (105) of the block (104) attached to the knob (16)
moves back and forth within the opening (17) in the space of the front panel (19).

As the slide arm (484) moves to the right, the pin (620) attached to it as shown in FIG. 10 moves with the arm (/184).

A pin (620) is provided to connect the main pivot 1 to the arm (622). The pin (620) is located within and juxtaposed within the opening (624) of the slide arm (484), thereby providing the ability to move the main pivot arm (622) connected thereto.

Enlarged head, washer or disk pin (620)
It can be placed in the top of the D-shaped opening (626) so that it can be installed by means of a locking nut on top or a washer. A D-shaped opening is shown in FIGS. 10 and 2. As you will see, a large washer (6
28), which allows the pin (62' O) to move freely around the inner periphery of the D-shaped dosing mouth, while the washer (628) attached to it allows the pin to slide out (pull). In place of the washer (62B),
The pin (620) itself can have an enlarged head, and the D-shaped mouth part (626) is prevented from moving any further.
Also, the pin (620) can be interlocked.

When moving to the right as shown in Figure 10, the D-shaped surface moves the main pivot arm (622), and the arm moves with the arrow (622) indicating engagement.
E), it swings to the right as shown in Figure 10. As slide arm (484) moves to the left as indicated by arrow (D), pin (620) engages the D-shaped mouth and moves main pivot arm (622).

The aforementioned plate (210) moves around a pivot point (294). This pivot point (294) allows the arm (622) to swing inward and outward.

The main pivot arm (622) has a pin, rivet or rotatable connection (630). This rotatable connection (630) allows the main pivot 1-arm (6
22) can move back and forth when driven by the slide arm (4, 84). As it moves back and forth, pins (634) with undercuts that engage slots (636) in arms (210) are used to locate arrows (E) and () for tape engagement and disengagement, respectively.
In direction D) the arm is moved back and forth.

The pin (634) does not move into the opening (640), which is used only for the installation of the bin (634) during the assembly process, and this pin fits into the keyhole slot (6
42) Exist within.

D at the main pivot arm (622) as shown.
The opening is important. This is because there is some chain play and the main pivot arm (622) is not at the pivot point (
630) and simultaneously rotates around the main pivot arm (630).
Insert the pin (634) installed in the key hole slot (6

0) can be moved relatively freely within it, and this is an important consideration. 2 pins (652) and (6
An omega or center spring (650) attached to the plate (210) causes the plate (210) to move when the plate (210) is driven by the main lever arm (622) to the position shown in FIGS. 10 and 11. It acts as a force. Omega spring (
650) is connected to the plate (210) by a pin (654) and to the frame by a pin (652). fact,
When the plate (216) having the pin (654) is driven to the engaged position in the direction of arrow (E) as shown in FIG. Biasing pin (654) in the inward engagement direction. Board (210

Therefore, the omega spring (650) is
It serves to bias the plate (210) into the engaged and disengaged positions shown in FIGS. 10 and 11, respectively.

Manure switches and monitors are installed to electromechanically check tape movement and placement. Dimensions shown in Figure 2
Uni limit switches (690) and (692) are installed to the right of limit I switch arms (694) and (606), respectively. The first switch determines whether the cartridge is in the eject secure mode or the non-write secure mode. This is done, as in all ANS 1 cartridges, by a special plug in the Kerr 1 heritage that can be rotated to indicate when the tape is safe for writing. one of the switches
One is used to direct the functionality of the controller and other elements of the system. Other switches determine if the cartridge is loaded and if the head is loaded.

To define features such as tape start and end, most ANSI tapes incorporate a series of holes to mark the end and beginning of the tape. These holes are read by optical sensors located within block (434). In particular, the optical sensors (700) and (702) are shown in FIG.
It receives light emitted from the light emitting diode (708) at an angular elevation of 45 degrees downward relative to the light emitting diode (710). Cartridge (2
The mirror (710) of 0) reflects light through holes in the tape to indicate the start or end position of the tape.

The light from the IED source (708) is transmitted through the optical sensor 1 (
700) and (702) and provides information -ioo- regarding tape start and end functions to the []-tape disc.

Adjustment of the light emitting diode with respect to the tape is a very important function. This is because if this is not set correctly for the indexing and positioning of the tape on the F plane and the B plane, the repulsion destination from the mirror (7”10) will be the optical sensor (700
) and (702). To adjust the position of the light emitting diode (708), move the diode (708) in and out, and then move the fixed plate (720)
) and fixed in place by means such as adhesive.

Alternatively, move the plate (720) inward and outward;
It can be adjusted by screws (722), (724) and (726). This allows the optical sensor (700) and (702
), the light emitting diode (708) can be adjusted in the inner and outer directions to allow respective readings at different angles.

The terminals of the light emitting diodes are shown as terminals (730) emerging from the light emitting diode (708) on the plate (720).These terminals and the respective light emitting diodes are of course shown in FIG. Moved back and forth above.

The above description is for the entire cartridge of this system, which includes a number of new components,
It includes systems and features that enhance the operational performance of cartridge tape drives.

This particular invention is believed to substantially enhance the utilization of the 4 inch section in the cartridge rather than the 6 inch section known in the prior art. This is generally based on the fact that cartridge positioning is particularly novel and useful for maintaining different functions of a tape cartridge drive. From this point of view, the claims should be read broadly.
