Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a magnetic head support device in a double-sided media magnetic recording device for magnetically recording on both sides of a flexible disk.

[Conventional technology]

A support device for a double-sided recording magnetic head of this type that is currently in general use is such that the first and second magnetic heads are attached to gimbal pieces attached to the tips of the first and second carriers. A structure is adopted in which the base of the carrier is fixed or swingable, and the first and second magnetic heads are pressed against the medium by a spring or the like.

[Problem to be solved by the invention]

Since the conventional support device for a double-sided recording type magnetic head has the above-described structure, it is difficult to position the first and second magnetic heads, and at the same time, productivity is poor.

That is, the setting positions of the first magnetic head and the second magnetic head require precision on the order of microns, but in the conventional structure, the first and second magnetic heads are first set on gimbal pieces, and then Because the gimbal pieces are assembled by sequentially gluing and screwing them onto the first and second carriers, errors in the processing accuracy and installation accuracy of each part overlap, resulting in large variations in the overall error of the assembled product, and in the final stage. It takes time to align the first magnetic head and the second magnetic head, resulting in poor productivity.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a double-sided recording type magnetic head support device which allows easy adjustment of the magnetic head position and which can be mass-produced.

[Means to solve the problem]

The present invention does not employ the conventional structure of adhering a magnetic head to a gimbal piece and then adhering the gimbal piece to a carrier, but instead uses a U-shaped rectangular piece bent at both ends of a flexible thin plate made of metal, plastic, etc. A gimbal part is formed in the gimbal part, a magnetic head is attached to the gimbal part, and an index for aligning the first magnetic head and the second magnetic head is provided at a predetermined position, such as a through hole, notch, or protrusion. is attached to the first and second carriers.

According to this structure, it is possible to mechanize the work of attaching the magnetic head to the gimbal part, which saves labor and improves productivity, and also greatly reduces the work of positioning and adjusting the first and second magnetic heads. This has the effect of simplifying the process and significantly improving the efficiency of assembly work.

〔Example〕

Embodiments of the present invention will be described below based on the drawings.

FIG. 1 is a perspective view of an embodiment of the present invention, and FIG. 2 is a sectional view, in which 1 and 2 are first and second magnetic heads, 3
4 is a first carrier; 5 is a second carrier consisting of a head 5a, a spring plate portion 5c, and a base 5b; 6 is a connecting piece; 7 is a second carrier head 5a; , 8 is a set screw, 9 is a cable,
10 is a cable connector.

FIG. 3 shows the structure of the strip 3 in an open state before the first and second carriers 4, 5 are attached to the connecting piece 6, and the first and second magnetic heads 1, 2 are Gimbal parts 11 and 12 are glued to fixed positions from the edge of the strip 3, and positioning holes 13 and 14 are provided at fixed positions from the edge of the strip 3.
is provided.

Both ends of the strip 3 are adhered to the first carrier 4 and the second carrier 5, respectively, leaving a bent part in the middle.

In this embodiment, the through holes 13 and 14 are provided so as to be located inside the carriers 4 and 5, so the through holes 13 and 14 are provided at the ends of each carrier 4 and 5 so that the through holes 13 and 14 can be seen through. , 14 larger through hole 15,1
6 (one not shown) is provided.

As described above, in the magnetic head support device according to the present invention, the gimbal parts 11 and 12 are provided at both ends of the strip piece 3, and the first and second magnetic heads 1 and 2 are attached to the gimbal parts. and second carrier 4,5
Since the structure is designed to be attached to the gimbal, the production of the gimbal part and the attachment of the magnetic head to the gimbal can be done using an integrated automatic machine, which allows mass production to be achieved compared to the conventional method, which was partially dependent on manual labor.
Processing and assembly accuracy errors can be reduced.

FIG. 4 shows the manufacturing process. In this case, the metal ribbon SR is flowed in the direction of the arrow, and first the gimbal parts 11, 12 and the through hole 13 are formed by press punching.
14, then the magnetic heads 1 and 2 are bonded to the gimbal parts 11 and 12 by a robot, and finally they are cut. The material of the strip is not limited to metal, but may also be made of plastic if the material is selected.

In addition, in the conventional structure, the extremely weak gimbal piece with the magnetic head attached had to be manually attached to the carrier, making the attachment work troublesome; however, the structure according to the present invention Since the work involves handling the strips 3, which are much longer than the gimbal pieces, the installation work is much easier. Furthermore, when aligning the first magnetic head and the second magnetic head, in the conventional structure, the first carrier and the second carrier were separate bodies, so the carrier swayed during adjustment, making the adjustment work difficult. However, in the present invention, since they are connected by the strips 3, it is easy to hold the carrier during adjustment work. Then, for position adjustment, use a microscope or a dowel pin for positioning. When using a microscope, see through the holes 13 and 14 and when they are aligned, or when using a dowel pin, insert the dowel pin through the through holes 13 and 14 and screw 8. By tightening them, the first magnetic head and the second magnetic head can be aligned.

[Different embodiments]

FIG. 5 shows a different embodiment, in which the through hole 1
3 and 14 are provided at a position where they can be seen outside the carrier. According to this structure, the through holes 15 and 16 are unnecessary.

6, 7, and 8 show other embodiments using protrusions or notches as indicators. The notches 18, 18 are shown in FIG. 8, the protrusion 17 and the notch 18.
It has been established.

Also, processing and assembly accuracy will be reduced, but
This indicator may be provided on the carrier instead of on the strip 3.

〔Effect of the invention〕

According to the present invention, mass production of magnetic head support devices can be achieved, and errors in processing and assembly accuracy can be reduced.
