[0001]
[Technical field to which the invention belongs]
The present invention relates to a magnetic head device, and more particularly to a magnetic head device that holds a magnetic head at a tip of a suspension and makes the magnetic head contact a recording medium with a predetermined pressing force.
[0002]
[Prior art]
A magneto-optical disk device has attracted attention as a recordable / reproducible disk device. The magneto-optical disk apparatus uses a disk on which a magnetic thin film is formed, and enables information to be recorded with high density by laser light.
[0003]
The magneto-optical disk apparatus irradiates a magnetic thin film from one surface of a magneto-optical disk (hereinafter simply referred to as a disk) with an intensity of laser light that can be heated above the Curie point or the temperature compensation point. Binary information is recorded by applying a vertical magnetic field to the portion of the surface facing the laser beam and reversing the magnetization direction of the magnetic thin film. When reproducing information, the disk is irradiated with laser light having an intensity that does not affect the magnetization direction of the magnetic thin film, and information is reproduced by detecting reflected light from the disk. Information reproduction was recorded using the fact that the amount of reflected light changes according to the direction of magnetization of the magnetic thin film by changing the optical characteristics of the magnetic thin film according to the direction of magnetization 2. Play value information.
[0004]
As described above, since the magneto-optical disk device requires a magnetic head device together with an optical pickup, the device tends to be thick, and a reduction in thickness is required.
FIG. 6 shows a configuration diagram of a magnetic head device mounted on a conventional magneto-optical disk device. 6A is a plan view and FIG. 6B is a front view.
[0005]
A conventional magnetic head device 21 includes a magnetic head 22 that applies a recording magnetic field to a disk, a support arm 23 that holds the magnetic head 22, a mounting plate 24 that holds the support arm 23 and moves the magnetic head 22 up and down, a magnetic head It is comprised from the flexible printed wiring board 25 for electrically connecting 22 with an external circuit.
[0006]
The magnetic head 22 has a configuration in which a substantially E-shaped core and a coil are wound around a slider that is in sliding contact with the disk, and a coil bobbin that engages the coil with the core is mounted.
The magnetic head 22 is held at one point of the support arm 23 and the support point P _{0 at} the tip, and is configured to follow the unevenness of the disk D. Further, a flexible printed wiring board 25 is soldered to the upper surface on the other end side of the magnetic head 22 to restrict the lowering of the magnetic head 22.
[0007]
The support arm 23 is made of a leaf spring material, a holding portion 23a for holding the magnetic head 22 is formed at the tip, and the other end is attached to the attachment plate 24 by a technique such as welding. When the mounting plate 24 is lowered in the direction of arrow B ₁ shown in FIG. 6B, the magnetic head 22 comes into contact with the disk with a certain force due to the elasticity of the support arm 23.
[0008]
The mounting plate 24 is made of a rigid body, and a support arm 23 is welded to one end thereof, and is fixed to a magnetic head device mounting portion configured to be movable in the direction of arrow B with a screw or the like. Further, the tip of the suspension arm regulating portion 24a for regulating the movement in the opposite direction (arrow B ₁ direction) is formed integrally with the disk of the magnetic head. The restricting portion 24 a extends to the mounting position of the magnetic head 22 and comes into contact with the magnetic head 22. For this reason, when the magnetic head 22 is flipped up in the direction of the arrow B _{1 in} FIG. 6 when an impact or the like is applied, the magnetic head 22 comes into contact with the restricting portion 24 a and the position of the magnetic head 22 is lowered below the mounting plate 24. regulate.
[0009]
FIG. 7 shows an operation explanatory diagram of a conventional example. FIG. 7A shows a head-down state where the disk is in sliding contact with the protective film of the disk, and FIG. 7B shows a head-up state where the disk is loaded or unloaded onto the apparatus.
In the head down state, the operating lever 26 that moves up and down the magnetic head 22 provided in the apparatus is lowered, so that the operating unit 24 moves in the direction of arrow B ₂ in FIG. It is contacted by the elastic deformation force of the support arm 23.
[0010]
In the head-up state, when the operation lever 26 is raised, the operation unit 24 is moved in the direction of arrow B ₁ in FIG. 8B, and the magnetic head 22 is separated from the disk D. In the head-up state, the support arm 23 is in a neutral state that is not elastically deformed, so that the magnetic head 22 vibrates up and down due to an impact or the like. At this time, in order to reduce the thickness of the device on which the magnetic head device 21 is mounted, the space above the magnetic head device 21 is limited to a necessary minimum.
[0011]
The magnetic head 22 jumps up by bringing the magnetic head 22 into contact with a restricting portion 24a provided at a position to be restricted above the magnetic head 22 so as not to exceed a certain height when the magnetic head 22 vibrates. Is regulated.
For this reason, in the conventional apparatus in which such a magnetic head device 21 is mounted, the flexible printed wiring board 25 of the magnetic head 22 and the height L ₀ from the surface of the disk D to the tip of the restricting portion 24a in the head-up state. The design is made such that another member is disposed above the height L ₁ in consideration of the protrusion of the terminal portion T to the upper portion of the restricting portion 24a for electrical connection.
[0012]
In the head-up state, the magnetic head 22 is held at only one point at the tip of the support arm 23. Therefore, the tip of the support arm 23 is deformed by the weight of the magnetic head 22, and the other end is directed toward the disk (arrow). ( ₁ direction), and the magnetic head 22 is tilted so that when the disk D is inserted from the direction of the arrow C, the tip of the magnetic head 22 is not caught by the disk D so that the disk D can be mounted smoothly. Was composed. At this time, the lowering of the magnetic head 22 is restricted by the flexible printed wiring board 25 soldered to the upper surface of the magnetic head 22, and the inclination angle θ ₂ of the magnetic head 22 is appropriately maintained.
[0013]
[Problems to be solved by the invention]
However, in the conventional magnetic head device, in the head-up state in which the disk is mounted / removed, the magnetic head fixes the slider to the tip of the suspension at one point and the other end is held by the flexible printed wiring board 25 to Since the lowering of the other end was restricted, the inclination of the magnetic head 22 was influenced by the arrangement of the flexible printed wiring board 25, and the lowermost end of the magnetic head 22 could not be determined. Therefore, it is necessary to set the distance h ₂ between the disk D and the magnetic head 22 with a margin, which hinders thinning.
[0014]
SUMMARY An advantage of some aspects of the invention is that it provides a magnetic head device that can be thinned.
