にして制振部材１０３が装着されている。2. Description of the Related Art A typical example of a conventional disk device is described in Japanese Utility Model Laid-Open No. 5-198075. This will be described below with reference to FIG. FIG. 5 is a perspective view of a head mounting mechanism of a conventional disk device. To explain the configuration, a magnetic head 101 for recording / reproducing on / from a magnetic disk and a gimbal spring 102 for supporting the magnetic head 101 are provided. The gimbal spring 102 includes the magnetic head 101 in the circumferential directions A and A of the magnetic disk. Two pairs of U-shaped notch grooves 12 for swinging each in a direction orthogonal to
2, 123 and tie bars 124, which are two pairs of swing support shafts.

りになってきた。In the above-mentioned disk device, the vibration of the magnetic head 101 is suppressed by the action of the vibration damping member 103 due to the attraction and slip of the magnetic head 101. As a result, the vibration of the magnetic head 101 causes the gimbal spring 102 to resonate. The generation of audible frequency vibrations is suppressed, and the operating noise of the device is reduced. In addition, this enables accurate recording and reproduction. However, although the initial purpose was achieved, the following drawbacks have become apparent from recent technological trends.

Have been developed, and electronic devices are being carried more frequently. Along with this, the risk of impact on the electronic device due to falling etc. increases, and the impact force is large,
The conventional impact resistance has become insufficient. As a matter of course, it is also necessary to improve the impact resistance of the disk device mounted on the electronic device.

Not only does the relative position with respect to the position at the time of adjustment move, but the contact between the magnetic head 101 and the magnetic disk becomes unstable, and normal recording / reproduction becomes impossible. Although illustration is omitted, there is a possibility that the intermediate frame 121 formed in the intermediate portion of the tie bar 125 or the two pairs of tie bars may be plastically deformed, and similar problems occur in these cases.

おり同様の機能を有している。Next, the function of the gimbal spring will be described using the gimbal spring 2 which supports the upper head 1. The material of the gimbal spring 2 is generally stainless steel or a copper alloy such as phosphor bronze, and is a thin plate having a thickness of about 0.05 mm to 0.2 mm. Its shape is as shown in FIG. The outer support portion 21 is a flat portion for fixing the gimbal spring 2, an intermediate frame 22, and a head support portion 23 is a flat portion for fixing the upper head 1. The outer support portion 21 and the outer support portion 21 are intermediate. The frame 22 is connected by a pair of tie bars 24, and the intermediate frame 22 and the head support portion 23 are also connected by a pair of tie bars 2.
5 are connected. In FIG. 1, the upper head 1 is supported below the gimbal spring 2. Thus, the upper head 1 is supported by the gimbal spring 2 and the upper carriage 4
When the angle variation occurs in the contact surface of the magnetic disk 7 with the head 1 by being attached to the head supporting portion 2
3 tilts with respect to the outer support portion 21 with the tie bar 24 or the tie bar 25 as a fulcrum, whereby the upper head 1 swings with respect to the upper carriage 4 and follows this fluctuation. The gimbal spring 12 that supports the lower head 11 has the same configuration and has the same function.

２の塑性変形を防止する事ができる。(Mode 1) As described above, the gimbal spring has a function of supporting the magnetic head so as to follow the fluctuation of the magnetic disk surface. To obtain this function, two pairs of tie bars are used. The rigidity of 24 and 25 must be set low, so that the impact resistance becomes very weak. As explained in the section of the prior art, when a large shock is applied to the disk device,
The tie bar 24 or the tie bar 25 is plastically deformed by the force generated by the mass of the upper head 1. Therefore, by disposing the elastic member 3 having a known elastic characteristic in advance over the outer supporting portion 21, the intermediate frame 22, and the head supporting portion 23 of the gimbal spring 2, in a process in which the gimbal spring 2 is deformed when an impact is applied, When the deformation further progresses than the elastic deformation region and tries to reach the plastic deformation region, the elastic member 3 suppresses the progress of the deformation and the gimbal spring 2 can be prevented from the plastic deformation.

有効である。The gimbal spring 2 in this embodiment has a shaft 2
Since the spring constant is symmetrical with respect to 5a, the elastic member 3 is also arranged so that its elastic force is symmetrical with respect to the shaft 25a. Further, it is desirable that the elastic member 3 has an appropriate viscosity. As a result, a desired component can be selected from the frequency components of the impact to exert the above effect. For example, by appropriately setting the viscous characteristics, the high frequency component included in the impact and the relatively low frequency component of the surface fluctuation of the magnetic disk are separated, and only the high frequency component included in the impact is selectively absorbed. The characteristics can be obtained. Furthermore, when the elastic member 3 is made viscous, the energy of the shock is absorbed by the internal loss of the elastic member 3, and the vibration of the gimbal spring system is damped faster. This effect is effective not only for impact, but also for absorption of vibration described in the section of the related art.

ることは極めて重要となる。The elastic member 3 in the present embodiment is used by adhering a sheet of polyester having a thickness of about 0.2 mm in the form of an adhesive tape to which an adhesive material is attached. The elastic members 3 are attached to the left and right sides of the gimbal spring 2 at positions apart from the center line 24a of the tie bar 24, symmetrically with respect to the center line 25a. This is gimbal spring 2
To prevent the tie bar 24 from being plastically deformed so as to be twisted in the radial direction of the magnetic disk 7.
Since the relative displacement amount of the head support portion 23 and the outer support portion 21 is larger at a position further away from the center line 24a of the, the elastic member 3 is attached so as to regulate the displacement amount at this position. Is because a larger effect can be expected.
When the gimbal spring 2 is plastically deformed in this direction, the off-track amount involved in the compatibility of recording / reproducing with respect to the magnetic disk 7, that is, the magnetic head from the track center of the standard magnetic disk (correctly recording / reproducing Since the amount of deviation of the gap portion) is increased, it is necessary to suppress a slight plastic deformation. Therefore, it is extremely important to suppress plastic deformation in this direction.

Since the head supporting portion 23 is disposed over the head supporting portion 23, it is possible to prevent the magnetic disk 7 from tilting in the circumferential direction, which is caused by the plastic deformation of the head supporting portion 23 such that the tie bar 25 is twisted. At the same time, the intermediate frame 22
It is also possible to prevent plastic deformation.

れる。(Mode 2) When the torsional rigidity of the tie bar 25 is relatively strong against an impact, there may be a case where only the tie bar 24 is plastically deformed so as to be twisted. As mentioned above, plastic deformation in this direction causes significant damage to device performance, especially compatibility. Therefore, in such a case, as shown in FIG. 2, the effect can be obtained if the elastic member 3 is attached only over the outer supporting portion 21 and the intermediate frame 22 of the gimbal spring 2.

Further, in the above-described embodiment, the gimbal spring 2 supporting the upper head 1 is used for the description, but it goes without saying that the gimbal spring 12 supporting the lower head 11 can be similarly applied. Finally, in the above embodiment, the disk device having the head mounting mechanism of the upper and lower gimbal spring structure has been described as an example. However, the lower head is fixed and the upper head is gimbal spring structure, or the lower head is gimbal spring and the upper head is fixed structure. It goes without saying that the present invention can also be applied to the gimbal spring portion of each disk device.

In this case, since it is necessary to make the inclination of the magnetic head follow the magnetic recording medium in order to stabilize the flying height, a gimbal structure similar to the above is required, and therefore, the above problems that can be solved by the present invention are solved. Because it has. In this case, it is necessary to change the specifications of the elastic member according to the weight of the magnetic head, but it is possible for those skilled in the art to easily change the design from the above description.
