Abstract

PURPOSE:To mechanize the fitting work of magnetic heads to gimbal sections, by forming the gimbal sections at both ends of a strip piece bent in U-shape and respectively fitting the magnetic heads to the gimbal section, then, fitting the strip piece equipped with indexes of through holes, notches, projections for positioning at prescribed positions in addition to the gimbal sections and magnetic head to the 1st and 2nd carriers. CONSTITUTION:Gimbal sections 11 and 12 are formed at both ends of a strip piece 3 and the 1st and 2nd magnetic heads 1 and 2 are respectively fitted to the gimbal sections 11 and 12, and then, the strip piece 3 is fitted to the 1st and 2nd carriers 4 and 5. Therefore, manufacture of the gimbals and fitting work of the magnetic heads to the gimbals can be made by integrated automated machines. Accordingly, mass production can be realized with this manufacturing method when compared with half-mechanized and half-manual conventional methods and, at the same time, errors in accuracy of finishing and assembling can be reduced.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement of a magnetic head support device in a magnetic recording device for double-sided media that performs magnetic recording on both sides of a 7LEXI-SOL disk.

[Conventional technology]

A supporting 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 second carrier is fixed or swingable, and the first and second magnetic heads are pressed against the medium by a spring or the like.

[Problem that the invention seeks to solve]

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

That is, since the setting pads, gimbals, and first and second carriers of the first and second magnetic heads are assembled by sequentially gluing and screwing, the q! rThe machining and stacking errors of parts and mounting accuracy errors overlap, resulting in large variations in the total error of assembled products, and it takes time to align the first and second magnetic heads at the final stage. P. Productivity was poor.

SUMMARY OF THE INVENTION Accordingly, it is an object of the present invention to provide a double-sided recording disk magnetic head P support device having a structure in which the position of the magnetic head can be easily adjusted and is also capable of reversing.

[Means to solve the problem]

The present invention does not adopt the conventional structure of gluing a magnetic head to a gimbal piece and layering the gimbal on a carrier, but instead attaches a gimbal part to both ends of a rectangular piece made of metal, plastic, etc. bent in a U-shape. A magnetic head is attached to the gimbal part, and a through hole, notch,
It has a structure in which indicators such as protrusions are attached to the first and second carriers.

According to this structure, the work of attaching the magnetic head to the gimbal part can be mechanized, which saves labor and improves productivity, and also simplifies the positioning and adjustment work of the magnetic head9. This has the effect of significantly improving efficiency.

〔Example〕

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

4 is a first carrier; d is a second carrier consisting of a head 5a, a spring plate portion 5C and a base 5b; 6;
1 is a connecting piece, 7 is an 8g2 elastic spring piece with a 5m carrier head, 8 is a set screw, 9 is a cable, and 10 is a cable connector.

In order to show the structure of the strip piece 3, Figure 3 shows the open state in which the first and second carriers 4 and 5 are attached to the connecting piece 6, and the first and second magnetic heads 1°2 are It is glued to a gimbal part 11.12 provided at a fixed position from the edge of the strip 3, and through holes 13, 14 for positioning are provided at a position one foot from the edge of the strip 3.

This strip piece 3 has both ends attached to the first carrier 4, leaving a bent part in the middle.
and the second carrier 5, respectively.

Note that through holes 15 and 16 (one not shown) are provided at the ends of each carrier 4 and 5 at positions that match the through holes 13 and 14, respectively.

As described above, the magnetic head support device according to the present invention has the following features:
Since the gimbal parts 11 and 12 are provided at both ends of the strip piece 3, and the first and second magnetic heads 1j2 are attached to the gimbal parts A and A, the structure is such that the first and second magnetic heads 1j2 are attached to the first and second carriers 4 and 5. Since the production of the gimbal and the attachment of the magnetic head to the gimbal can be performed using a fully automatic machine, it is possible to achieve greater customer preference than the conventional method, which relied on manual labor, and to reduce errors in processing and assembly accuracy. can be reduced.

Figure 4 shows the manufacturing process. In this case, the metal ribbon SR is flowed in the direction of the arrow, first the gimbal part 11.12 and the through hole 13.14 are formed by Sores punching, and then the robot The magnetic head 1°2 is gimbaled by s11,
12 and finally cut. The material for the strips is not limited to metal; plastic can also be used if the material is selected.

In addition, with conventional electronic devices, the gimbal, which is an extremely weak piece with a magnetic head attached to it, had to be manually attached to the carrier, making the installation process troublesome.
The structure according to the present invention is much easier to install because the work involves handling a much longer strip 3 than the conventional zipper piece.

Furthermore, when aligning the magnetic head, with the conventional structure, the first carrier and the second carrier were eight separate bodies, which caused the carriers to wobble during adjustment, making adjustment work difficult.
In the present invention, it is sufficient to see through the connection using the strip 3 and tighten the screw 8t when the connection is matched.

[Different embodiments]

In the embodiment shown in the drawings, the alignment index is a through hole, but a notch or a protrusion may be provided on the edge.

Furthermore, this indicator may be provided on the carrier instead of the strip 3, although the assembly accuracy for processing 1 will be lowered.
