Detailed Description of the Invention

[0001]

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

[0002]

2. Description of the Related Art In recent years, a floppy disk device for recording and reproducing data from a magnetic recording medium via a magnetic recording head has been put into practical use.

As shown in FIG. 4, a conventional magnetic head assembly includes a magnetic head 2 which is in contact with a magnetic recording medium 1 and has a gap portion 2a in a front core 2b, and a winding body 11 which includes a terminal portion 11a. , A back core 2c, a flexible printed circuit 12, and a plate member 13. That is, the electrically connecting portion between the winding body 11 for supplying and receiving the electric signal to the magnetic head 2 and the flexible printed circuit 12 for transmitting the electric signal is configured such that the plate material 13 is interposed between the magnetic recording medium 1 and the magnetic recording medium 1. However, the electrical junction has a structure perpendicular to the surface of the magnetic recording medium 1.

[0004]

In the above-described conventional magnetic head assembly, the electrical connection between the winding body that supplies an electrical signal to the magnetic head and the flexible printed circuit that transmits the electrical signal is magnetic. Since the magnetic head assembly is located through the plate material when viewed from the recording medium, there is an obstacle that the height of the magnetic head assembly does not become small in order to make the floppy disk device thinner. Therefore, in response to market needs such as notebook PCs that are becoming lighter, thinner, shorter, and smaller,
There was a big problem that the floppy disk device did not become thin.

The present invention will be described below with reference to the drawings.

FIG. 1 is an exploded perspective view showing a first embodiment of the magnetic head assembly of the present invention. In the figure, the magnetic head assembly of the present invention has a front core 2b having a gap portion 2a for recording or reproducing on the magnetic recording medium 1 to form the magnetic head 2. Further, the winding body 3 having the terminal portion 3a forming an electrical joint with the flexible printed circuit 4 and the back core 2c constitute a magnetic circuit.

The magnetic head 2 is fixed to the plate member 5. Here, the plate member 5 is a fixed plate member.

As shown in FIG. 1, an electrical joint between the terminal portion 3a of the winding body 3 and the flexible printed circuit 4 is arranged between the magnetic recording medium 1 and the plate member 5. The arrangement direction of the terminal portions 3a is the same as the inclination of the gap portion 2a of the magnetic head 2. The flexible printed circuit 4 may be attached to the plate member 5 or may be adjacent to it.

FIG. 2 is an exploded perspective view showing a second embodiment of the present invention. In the figure, the basic configuration of the second embodiment is the same as that of the first embodiment described above, but the arrangement direction of the terminal portions 3a of the winding body 3 is the inclination of the gap portion 2a of the magnetic head 2. The structure is inclined by 90 °. The terminal portion 3a is joined to the flexible printed circuit 6 on the plate member 5.

FIG. 3 is an exploded perspective view showing a third embodiment of the present invention. In the figure, the basic structure of the third embodiment is the same as that of the first embodiment, but the magnetic head 2
It is shown that the member 7 for holding can be movable.

The magnetic head 2 contacts the magnetic recording medium 1 to record / reproduce information. However, the contact of the magnetic head 2 may be impaired due to the inclination of the magnetic head only with a fixed plate material. That is, by applying the movable plate member 7, it is possible to adjust so as to obtain an appropriate hit.

In any of the embodiments, the electrical joint between the terminal portion and the flexible printed circuit may be formed by using any one of solder, conductive paint and conductive resin.

[0021]

As described above, according to the present invention, in the magnetic head assembly of the floppy disk drive, the electrical connection portion between the winding body and the flexible printed circuit is provided between the recording medium and the plate member that holds the magnetic head assembly. The height of the magnetic head assembly can be suppressed to a small value because the magnetic head assembly is arranged in the. Therefore, the device itself can be made thinner.
