DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic head device, and more particularly to a magnetic head device used in a floppy disk device.

[0002]

2. Description of the Related Art A conventional magnetic head 51 is, for example, as shown in FIG. 4, a slider assembly 53 incorporating a magnetic core 52 for magnetic recording and reproduction, and a gimbal-shaped leaf spring 54.
It was constructed by bonding and.

In this case, the leaf spring 54 has a central portion to which the slider assembly 53 is fixed, an outer frame portion for supporting the central portion, and an intermediate portion arranged between them, and these are mutually connected. Are provided with connecting portions at two positions on opposite sides, respectively, which allows smooth vertical movement of the slider assembly 53.

On the other hand, in recent years, in order to reduce the size of the entire apparatus, a proposal has been submitted for disposing the entire magnetic head 51 inside a medium cartridge (Japanese Patent Laid-Open No. 4-129).
059, JP-A-62-12975, USP
5, 237, 474).

[0005]

However, in the above-mentioned conventional example, when the gimbal-shaped leaf spring 54 is arranged inside the medium cartridge, as shown in FIG.
Since the gimbal-shaped leaf spring 54 has a large size, there is an inconvenience that a space cannot be taken. Further, since the position of the gimbal-shaped leaf spring 54 sticks out of the medium cartridge, there is an inconvenience that the device is made thin. Further, since the position of the leaf spring 54 is farther than the medium sliding surface of the slider, the slider is apt to vibrate, and the reliability is lowered.

[0006]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a magnetic head device which improves the inconveniences of the prior art, and in particular, makes the entire device thinner and improves the vibration resistance.

[0007]

According to the present invention, in a magnetic head comprising a slider assembly having a magnetic core and a gimbal-shaped leaf spring fixed to the slider assembly, the gimbal-shaped leaf spring is The gimbal-shaped leaf spring is formed to have a size inside the outermost portion of the slider assembly, while being formed by the outer frame portion and the central portion via the connecting portion. I am collecting. This aims to achieve the above-mentioned object.

[0008]

[Operation] It is possible to reduce the overall size of the gimbal-shaped leaf spring 4 and equip it inside the medium cartridge 31. Therefore, the position of the leaf spring 4 can be adjusted to the position of the slider assembly 3 with the miniaturization of the entire apparatus. Medium (floppy disk) 3
Since it can be set at a position close to the sliding surface with respect to 3, the occurrence of stick-slip vibration of the slider with the center of the leaf spring as the fulcrum is suppressed.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS.

1 to 3, the magnetic head device 1 comprises a slider assembly 3 having a magnetic core 2 and a gimbal-shaped leaf spring 4 fixed to the slider assembly 3.

As shown in FIG. 2, the gimbal-shaped leaf spring 4 is arranged between a central portion 4A to which the slider assembly 3 is fixed, an outer frame portion 4B for supporting the central portion 4A, and an intermediate portion 4B. And an intermediate portion 4C, and there are two connecting portions 4 ₁ , on the opposite sides of each other.
4 _2, 4 _3, 4 ₄ comprise are configured.

The size of the outer frame portion 4B of the gimbal-shaped leaf spring 4 is formed so as to be located inside the outermost portion of the slider assembly 3 described above.

Further, the slider assembly 3 is actually shown in FIG.
As shown in FIG. 5, the gimbal-shaped leaf spring 4 is suspended and supported by the central portion 4A. Furthermore, the gimbal-shaped leaf spring 4
The outer frame portion 4B is the arm portion 5 of the head support mechanism.
It is drooped and supported uniformly.

A slider assembly 3 having a magnetic core 2
As described above, the surface to be bonded to the gimbal-shaped leaf spring 4 is formed to be smaller inward than the outer shape of the slider assembly 3. Therefore, the central portion 4A of the gimbal-shaped leaf spring as shown in FIG. 2 can be designed small, and the connecting portions 4 ₁ , 4 ₂ , 4 ₃ , 4 ₄ can be moved to the slider assembly 3 as shown in FIG. Can be placed inside the outermost part of the.

Thus, the overall size of the gimbal-shaped leaf spring 4 is reduced, and as shown in FIG.
It became possible to put the leaf spring 4 inside the car. Here, the lower head portion 12 of FIG. 3 is generally fixed,
No gimbaled leaf spring is used.

The position of the leaf spring 4 is determined by the medium cartridge 31.
Among these, it is preferable that the slider assembly 3 is as close as possible to the sliding surface with the medium (floppy disk) 33. This is because stick-slip vibration of the slider with the center of the leaf spring as the fulcrum is less likely to occur. Therefore, the height of the slider assembly 3 is set to be thin in this embodiment as well, which suppresses the occurrence of stick-slip vibration of the slider.

[0017]

Since the present invention is constructed and functions as described above, according to this, since the outer frame portion of the gimbal-shaped leaf spring is provided inside the outermost portion of the slider assembly, the leaf spring is included. Since the entire magnetic head can be accessed inside the medium cartridge, and the thickness of the upper head can be reduced, the device can be made thinner, and the leaf spring can be attached to the medium sliding surface of the slider. As the slider approaches, the stick-slip vibration of the slider can be suppressed, and the reliability of the entire apparatus can be improved, so that an excellent magnetic head apparatus which has not been available can be provided.
