In FIG. 3, a magnetic head supporting device includes a magnetic head 1 for reading and writing information from and on a recording medium, a gimbal 2 provided with a slit 2a so as to follow the surface of the recording medium, and the magnetic head 1 described above. Lead not shown
A flexible printed circuit board (hereinafter, simply referred to as FPC) 3 for transmitting information between the light circuits, and the gimbal 2
And a damper member 4 for laterally extending over the slit 2a formed therein and for damping the movement of portions of the gimbal 2 that are displaced relative to each other. The terminal portion 1a provided on the magnetic head 1 is fixed to the FPC 3 via a gimbal 2 by soldering.

According to the above conventional magnetic head supporting device,
Vibration is applied to the magnetic head 1 by the rotation of the recording medium in the A direction, but a damper member 4 provided separately from the FPC 3 is provided.
Gimbal 2 by limiting the movement of gimbal 2
Resonance can be prevented.

[0005]

However, according to the above-mentioned conventional magnetic head supporting device, in order to effectively prevent the resonance of the gimbal 2, the damper member 4 is made of a soft material and is compact in space. Therefore, the mounting work of the damper member 4 was very difficult.

Moreover, when the damper member 4 is mounted horizontally on the slit 2a of the gimbal 2, it is very difficult to position the damper member 4, as shown in FIG.
However, there is a problem in that workability varies as shown in FIG.

When the damper member 4 is fixed near the soldered terminal portion 1a, the damper member 4 may be peeled off for stress relaxation as shown in FIG.
Further, as shown in FIG. 7, in the gimbal 2 in which the cutout portion 2b is formed so as to allow the terminal portion 1a of the magnetic head 1 to escape, there is a problem that there is no place to attach the damper member 4.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a magnetic head supporting device capable of improving workability and preventing gimbal resonance. Especially.

[0009]

In order to achieve the above object, the present invention provides a magnetic head for reading and writing information on a recording medium, and a slit so that the magnetic head can move following the movement of the recording medium. A magnetic head supporting device having a gimbal provided and an FPC in contact with the gimbal for transmitting an information signal of the magnetic head, wherein a horizontal portion provided at an end of the FPC horizontally extends over the slit. It is characterized by being fixed.

[0010]

With this structure, since the laterally mounted portion provided on the FPC is laterally fixed on the slit of the gimbal, it is possible to reduce the number of magnetic parts while reducing the number of parts without providing any special parts such as damper members. Resonance of the gimbal due to head vibration can be prevented.

Moreover, the positioning operation for horizontally extending the horizontal portion on the slit of the gimbal is performed at the same time as the operation of soldering the terminal portion of the magnetic head to the FPC without increasing the number of steps. Moreover, since the FPC itself provided with the laterally extending portion has a size that is easy to handle, the workability can be significantly improved.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A magnetic head supporting device of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing the outline of a magnetic head supporting device of the present invention. FIG. 2 is a front view of the same. The same parts as those in the prior art are designated by the same reference numerals, and the description of the configuration and operation thereof will be omitted.

In FIG. 1, the magnetic head supporting apparatus of the present invention comprises a magnetic head 1 having a terminal portion 1a and a slit 2a.
And a flexible printed circuit board (hereinafter, simply referred to as FPC) 10.

At both ends of the FPC 10, lateral ends 11 are formed by extending the both ends.
A double-sided tape (not shown) is attached to the surface of the gimbal 2 on the side of the gimbal 2, and the gimbal 2 and the FPC 10 are bonded to each other.

In the FPC 10, the terminal portion 1a of the magnetic head 1 is fixed by soldering via the gimbal 2, and the gimbal 2 is fixed by double-sided tape. At the same time, the F
The slit 2a of the gimbal 2 is laid horizontally via a double-sided tape adhered to the back surface of the laterally extending portion 11 of the PC 10 to dampen the movement of the portions of the gimbal 2 that are relatively displaced from each other.

According to the above-described embodiment, the gimbal 2 is fixed by laterally fixing the laterally extending portion 11 provided on the FPC 10 on the slit 2a of the gimbal 2 without providing a dedicated member such as a damper member. Since the movement of the gimbal 2 can be limited, the number of parts can be reduced and the resonance of the gimbal 2 due to the vibration of the magnetic head 1 can be prevented.

Moreover, the positioning work for horizontally mounting the horizontal bridge portion 11 on the slit 2a of the gimbal 2 does not require additional man-hours, and the terminal portion 1a of the magnetic head 1 does not have to be added.
Is performed at the same time as the operation of soldering the FPC 10 to the FPC 10, and the FPC 10 itself provided with the laterally extending portion 11 has a size that is easy to handle, so that the workability can be significantly improved.

In the above-described embodiment, the two laterally extending portions 11 are provided at both ends of the FPC 10. However, if the two horizontally extending portions are provided on the slit 2a of the gimbal 2, the position of the horizontally extending portion 11 and The number is not limited to this.

Further, in the above-described embodiment, the FPC 10 itself is provided with the laterally extending portion 11, but if the laterally extending portion 11 is provided only on the double-sided tape attached to the back surface of the FPC 10, the double-sided tape is provided. Since it is sufficient to improve only the above, not to mention the above effect, it is possible to further reduce the cost.

[0020]

According to the magnetic head supporting apparatus of the present invention configured as described above, the horizontal cross section provided on the FPC is laterally arranged on the slit of the gimbal without providing a dedicated part such as a damper member. Since the gimbal can be restrained from moving by being fixed so as to be suspended, resonance of the gimbal due to vibration of the magnetic head can be prevented while reducing the number of parts.

Moreover, the positioning operation for horizontally extending the horizontal portion on the slit of the gimbal is performed at the same time as the operation of soldering the terminal portion of the magnetic head to the FPC without adding an additional man-hour. Moreover, since the FPC itself provided with the laterally extending portion has a size that is easy to handle, the workability can be significantly improved.
