Abstract
A magnetic head that is excellently adapted to a magnetic core reduced in thickness. When a magnetic core which is reduced in thickness for adaptation to a high recording density is inserted in an opening of a size conventionally formed in a magnetic head of a standard recording density type, a spacer made of a material equivalent or identical to that of a slider is inserted between the magnetic core and the inner wall of the opening. The magnetic core is positioned by means of projections formed on the inner wall of the opening and the spacer. Then, glass as a sealing material is poured into gaps formed in the opening by the magnetic core, the inner wall of the opening and the spacer. The inserted spacer reduces a space volume for the glass to be poured. Further, since the spacer is made of the material equivalent or identical to that of the slider, a partial abrasion at a sliding surface of the slider sliding on a recording medium can be eliminated.
