Abstract

PURPOSE:To lower a total cost by simplifying a working processing process and furthermore, to prevent an adverse effect due to the aggravation of the posture of a magnetic head by a head cable by placing the pattern of the head cable on the surface of a gimbal spring, and integrating both components. CONSTITUTION:The title device is constituted in such a way that the pattern 2 of the head cable is placed on the surface of the gimbal spring 1 and both components are integrated. In other words, the wiring pattern 2 which fulfills the role of the head cable to connect a head core such as a recording ad reproducing head core or an erasing head core, etc., to a floppy disk drive main body is integrated with the gimbal spring 1 via a tape, a film, and an insulating material such as a coating agent, etc. In such a way, it is possible to omit the bonding process of the gimbal spring with the head cable, and also, to prevent the posture of the magnetic head from being aggravated by the head cable.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a gimbal spring that supports a magnetic head of a floppy disk drive (FDD).

[Prior Art] FIG. 4 is a perspective view showing a conventional magnetic head support device used in a magnetic head device. In the figure, 11 is a head core for recording and reproduction, 12 is a head core for erasing, and 13 is a head core for erasing.
1 is a recording/reproducing coil, and 14 is an erasing coil. 15
．． Reference numeral 16 denotes a back bar made of a magnetic material such as ferrite for forming a closed magnetic path in the magnetic circuit of the recording/reproducing RAD core 11 or the erasing RAD core 12. 17 is a gimbal spring that supports the magnetic head; 18 is a recording/reproducing head core 11. This is a head cable made of a flexible printed circuit board that connects the eraser rad core 12 and the FDD main body (not shown).

[Problems to be Solved by the Invention] In the conventional magnetic head support device as described above, the gimbal spring 17 and the head cable 18 are configured separately, so they must be bonded to each other. In this case, since it is necessary to center the magnetic head, the processing process becomes complicated, and the head cable 18 deteriorates the posture of the magnetic head.

The present invention was made to solve these problems, and an object of the present invention is to provide a magnetic head support device that can omit the process of bonding the gimbal spring and the head cable, and can also prevent the deterioration of the posture of the magnetic head due to the head cable. do.

[Means for Solving the Problems] A magnetic head support device according to the present invention has a structure in which a pattern of a head cable is placed on the surface of a gimbal spring to integrate the two.

[Function] In the magnetic head support device of the present invention, the head cable pattern is placed on the surface of the gimbal spring and integrated, so the processing process is simplified.
Furthermore, the adverse effects of changes in the attitude of the magnetic head due to the head cable can be prevented.

[Embodiment] FIG. 1 is a perspective view showing a gimbal spring in a magnetic head support device according to an embodiment of the present invention, and FIG. 2 is a partial sectional view of the gimbal spring shown in FIG. 1.

In the figure, l is a gimbal spring that supports the magnetic head, 2 is a radonia for recording and reproduction, and a rad core for erasing (
This wiring pattern serves as a head cable for connecting the head core (both not shown) and the FDD main body (not shown). This wiring pattern 2
As shown in the figure, it is configured to be integrated with a gimbal spring 1 via an insulating material 3 such as tape, film, or paint.

Note that the embodiment shown in FIGS. 1 and 2 above shows a case in which the wiring pattern 2 is dispersed on the surface of the gimbal spring 1, but other embodiments of the invention shown in FIG. As in the example, the wiring pattern 2 may be concentrated on a part of the surface of the gimbal spring l,
The same effects as in the above embodiment are achieved.

[Effects of the Invention] As explained above, in the present invention, in a magnetic head support device, the pattern of the head cable is placed on the surface of the gimbal spring and the two are integrated, so that the processing process is simplified. Therefore, the overall cost is reduced, and furthermore, it has excellent effects such as being able to prevent the adverse effects of deterioration of the posture of the magnetic head due to the head cable.
