Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a method for manufacturing a magnetic head, and particularly to a method for assembling the magnetic head with an arm.

(2) Background of the technology Figure 1 shows a magnetic head used in a magnetic disk device, in which 1 is a magnetic core, 2 is a center slider rail, 3 is a coil, and 4 and 4'.
indicate the side slider rails. This magnetic head is attached to a leaf spring 5 as shown in FIG. 2 and is used by floating above a magnetic disk 6 which rotates at high speed. Buoyant force is generated by the side slider rails 4 and 4' and is balanced by the spring 5 to give the magnetic head 7 a constant flying height. In this state,
The magnetic head 7 and the magnetic disk 6 exchange information magnetically. In this case, if the center slider rail 2 of the magnetic head is not aligned with the track of the magnetic disk, the write or read signal will be weak. For this reason, it is necessary to align the directions of the tracks of the magnetic disk and the end faces of the center slider rail or side slider rail of the magnetic head.

(3) Prior art and problems Figure 3 shows a magnetic head assembly.
is a magnetic head, 8 is a leaf spring that supports the magnetic head,
Reference numeral 9 indicates an arm, and 9a indicates a reference plane of the arm. Conventionally, this magnetic head assembly has been assembled so that the center slider rail of the magnetic head 7 is parallel to the reference plane 9a of the arm 9 to satisfy the above requirements. The parallelism between the reference plane 9a of the arm 9 and the center slider rail of the magnetic head 7 means that the reference plane 9a is fixed to an X-Y table and the deviation of the center slider rail of the magnetic head when it is moved a certain distance. I measured it and found out the parallelism. At the same time, the dimension between the reference surface 9a and the center slider rail of the magnetic head was also adjusted. However, this method has disadvantages in that it is cumbersome to operate because it involves moving the X-Y table, and it takes a long time for adjustment.

(4) Purpose of the Invention In view of the above-mentioned conventional drawbacks, an object of the present invention is to provide a method for manufacturing a magnetic head that does not require an X-Y table and allows easy adjustment and assembly of the magnetic head assembly. It is.

(5) Structure of the Invention According to the present invention, this purpose is to form a magnetic head assembly by attaching the other end of the spring plate 17 with the magnetic head 16 attached to one end to the arm 15 having the reference surface 15a. In the magnetic head manufacturing method, a reference block 11 is fixedly supported by contacting the arm 15 and its reference surface 15a, and a slider of the magnetic head 16 is provided at a position of a prescribed distance from the reference block 11 to the magnetic head 16. The reference surface 15a of the arm 15 is brought into contact with the reference surface 11a of the reference block 11 and fixed using a jig equipped with a glass plate 12 on which two parallel lines 19 and 20 are drawn to indicate the permissible range of inclination of the rail. By providing a method for manufacturing a magnetic head, the spring plate 17 is fixed to the arm 15 so that the slider rail is supported and accommodated within two parallel lines 19 and 20 of the glass plate 12. achieved.

(6) Examples of the invention Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 4 is a diagram for explaining a jig with which the method of manufacturing a magnetic head according to the present invention can be carried out. In the figure, reference numeral 10 indicates a substrate of the jig, 11 a reference block, 12 a glass plate, and 13 a support member that supports the glass plate and is rotatable at pivots 14 and 14', respectively. Note that 15 is an arm of the magnetic head, 16 is a magnetic head, and 17 is a spring plate that supports the magnetic head and is fixed to the arm.

This jig has a reference block 11 on a jig substrate 10.
A support member 13 is rotatably provided on the pivot 14, 14', and a glass plate 12 is attached to the support member. Two parallel lines 19 and 20 are drawn on this glass plate as shown in the enlarged view of FIG.
These two parallel lines 19 and 20 are the reference block 11.
parallel to the reference plane 11a, and the reference plane 11a
The distance from the center slider rail 16a of the magnetic head 16 is a specified dimension, and the distance W between the two parallel lines is the permissible width of the inclination of the center slider rail 16a of the magnetic head 16.

The method of the present invention using such a jig will be explained next. First, the glass plate 12 of the jig 10 shown in FIG.
Rotate the support member 13 to move it away from the position shown in the figure. Next, the reference surface 11a of the reference block 11
The reference surface 15a of the arm 15 of the magnetic head assembly is
After abutting and fixing (the fixing method is not shown), the glass plate 12 is returned to its original position so that it is placed above the magnetic head 16. After looking at the magnetic head 16 through the glass plate 12, loosen the screw 18 and adjust it so that the center slider rail 16a fits within the two parallel lines 19 and 20 drawn on the glass plate 12, as shown in FIG. Fix it.

By doing this, the center slider rail 16a of the magnetic head 16 can be assembled so that the distance and parallelism from the reference plane of the arm 15 are within specified values.

(7) Effects of the Invention As explained above in detail, the magnetic head manufacturing method of the present invention allows adjustment and assembly of the magnetic head assembly without requiring an X-Y table by using a simple jig. The effect of making it easier is that it has a great effect.
