Abstract

PROBLEM TO BE SOLVED: To manufacture two different shape slider elements by using only one kind of metallic mold by forming two split slider elements by means of cutting one slider mold. SOLUTION: One slider mold 20 is formed from one kind of ceramic material with one kind of metallic mold. On the top of this slider mold 20, air bearing surfaces(ABS) 23, 24 are formed to come into slidable contact with a magnetic disk, and a space 25 is formed inside for incorporating a core, a bobbin, and a winding. This slider mold 20 is split into two slider elements 21, 22 by cutting it along a cut line 26. Since joining surfaces 21A, 22A appear along the cut line 26 on the two-piece slider elements, it is possible to fix the core interposed between the two as in a slider formed as another part.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for manufacturing a magnetic head in which a core is interposed and fixed between two divided slider elements.

[0002]

2. Description of the Related Art There are various types of magnetic heads that come into sliding contact with a magnetic disk. For example, FIG. 3 shows an example of assembling a magnetic head in which a core is interposed and fixed between two divided slider elements. In the figure, reference numerals 11 and 12 denote two-divided slider elements, which are fixed (integrated) with a core 13 interposed therebetween.

[0003] 11A and 12A are slider elements 1 respectively.
1 and 12 are opposed joint surfaces. Bobbins 16 and 17 around which windings 14 and 15 are wound are mounted on the core 13.
The winding 14 is for recording / reproducing, and the winding 15 is for erasing. Behind the core 13, a back core 18 is attached.

[0004]

The slider elements 11, 12 described above are manufactured as independent parts. Therefore, in the case of a molded product, two types of dies are required, which increases the cost. This is a problem to be solved by the present invention.

An object of the present invention is to provide a method of manufacturing a magnetic head which can manufacture two slider elements having different shapes by using only one type of mold, thereby making it possible to reduce the price of the magnetic head. And

[0006]

SUMMARY OF THE INVENTION The object of the present invention is as follows.
In a method of manufacturing a magnetic head in which a core is interposed between divided slider elements and fixed, the two divided slider elements are formed by cutting one slider molded product. Can be achieved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below in detail with reference to embodiments shown in the drawings. FIG. 1 is a perspective view showing one embodiment of the present invention. FIG. 1A shows one slider molded product 20. The molded article 20 is formed by molding a wear-resistant ceramic material with one type of mold.

An air bearing surface (ABS) 2 serving as a sliding contact surface with a magnetic disk is provided on the upper part of the slider molded product 20.
3 and 24 are formed, and a space 25 for accommodating a core, a bobbin, a winding and the like is formed therein. In the present invention, this slider molded product 20 is cut along a cutting line 26 and divided into two slider elements 21 and 22 shown in FIG. The cutting line 26 is set in a direction to divide the ABS 24 on the core housing side into two. 24A and 24B are divided AB
Each part of S24.

Since the joining surfaces 21A and 22A appear along the cutting line 26 in the slider elements 21 and 22 divided into two parts, similar to the sliders 11 and 12 formed as separate parts shown in FIG. It can be fixed by interposing a core between them.

FIG. 2 is a perspective view after another division showing another embodiment of the present invention. As in this example, the slider molded product 20 may be chamfered in advance. 21B, 22B
Are R-processed outside the ABSs 23 and 24. This can also be formed simultaneously with the mold at the time of molding.

[0011]

As described above, according to the present invention, it is possible to manufacture two slider elements having different shapes by using only one type of mold, thereby making it possible to reduce the cost of the magnetic head. Can be provided.
