Abstract

PURPOSE:To suppress the vibration of a plate spring and to ensure stable recording and reproducing jobs by sintering a soft elastic member and fixing it to the plate spring containing a slider. CONSTITUTION:A slider 2 is adhered approximately at the center of a plate spring 4 and this spring 4 is attached to a base 7 by an adhesive. Then a soft elastic member 6 is fixed to the spring 4 by sintering. Thus the vibration of the spring 4 is absorbed by the member 6 and reduced greatly. This always secures the stable magnetic recording and reproducing jobs. The member 6 is just required on a single side of the spring 4 or at least at a limited part of both sides of the spring 4, respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a magnetic head, and particularly to a magnetic head used in a floppy disk device.

[Conventional technology]

A magnetic head used in a conventional floppy disk device has a structure in which a flexible flat medium 1 is sandwiched between sliders 2.3, as shown in FIG. The slider 2 is mounted on a plate spring 9, and the plate spring 9 is fixed to the base 7. Further, the load arm 10 that holds the slider 3 is fixed to the base 7 by screwing the plate metal member 11 integrated therewith to the base 7 via the holding plate 12, and the load spring 13 The configuration is such that pressure is applied to the medium 1 by sandwiching it therebetween. The holding portion of the slider 2 is constructed by mounting the slider 2 on a plate spring 9 and fixing the plate spring 9 to a base 7 having a protrusion 8, as shown in FIG.

As described above in detail with reference to FIG. 6, such a conventional magnetic head is provided with a load spring 13 on the opposite side of the slider 2 across the medium 1, and uses this pressure to move the load arm 10 toward the medium. It is configured so that it is forced to 1.

Further, in order to maintain good adhesion between the slider 2 and the medium 1, the slider 2 is pressed against a protrusion 8, which is a part of the base 7, via a plate spring 9.

[Problem that the invention seeks to solve]

In the above-described conventional magnetic head, the medium is rotated while being sandwiched between the sliders, so that the plate-shaped springs vibrate via the slider due to the undulation of the medium.

The vibration of the plate-shaped springs causes a decrease in the adhesion between the medium and the slider, and the vibrations may also become abnormal vibrations accompanied by the generation of abnormal sounds.

Therefore, the conventional magnetic head has the drawback that stable magnetic recording and reproducing cannot be performed due to the vibration of the plate-shaped wings.

SUMMARY OF THE INVENTION An object of the present invention is to provide a magnetic head that suppresses the vibration of a plate spring and enables stable magnetic recording and reproduction.

[Means for solving problems]

The magnetic head of the present invention is characterized in that a soft elastic material is fixed by sintering to at least part of one or both surfaces of a plate-like spring on which a slider is mounted.

〔Example〕

Next, the present invention will be explained in detail with reference to the drawings.

FIG. 1 is a sectional view showing one embodiment of the present invention.

In FIG. 1, the slider 2 is adhesively fixed to approximately the center of the plate spring 4. As shown in FIG. This plate spring 4 is fixed to the base 7 with an adhesive.

A soft elastic material 6 is sintered and fixed to the plate spring 4.

According to the present invention, since the soft elastic material 6 is fixed, the vibration generated in the plate-like spring 4 is absorbed by the soft elastic material 6, and the vibration of the plate-like spring 4 becomes extremely small, resulting in stable magnetic recording. and can be played. It is effective if the soft elastic material 6 is provided on at least a portion of one or both surfaces of the plate spring 4.

2 and 3 show an example in which the soft elastic material 6 is fixed to a part of the slider mounting surface of the plate spring 4, and FIGS. 4 and 5 show the slider mounting surface of the plate spring 4 and the soft elastic material 6. This is an example in which a soft elastic material 6 is fixed to the entire surface on the opposite side.

Furthermore, since the soft elastic material 6 is fixed by sintering, the fixing position can be arbitrarily selected, and the fixation of the soft elastic material 6 is very stable. Further, the vibration of the plate spring 5 can be reduced by fixing the soft elastic material 6 to the plate spring 5 on the opposite side of the plate spring 4 with the medium 1 in between by the same means. Needless to say, stable magnetic recording and reproduction are possible.

〔Effect of the invention〕

As explained above, the magnetic head of the present invention reduces the vibration of the plate spring by fixing a soft elastic material to the plate spring by sintering, thereby making it possible to perform stable magnetic recording and reproduction at all times. There is an effect that can be done.
