Abstract

PURPOSE: To establish the head of long life with the wear proof performance improved, by coating the part other than the magnetic gap of the surface in contact with the recording media by means of the protective layer imbedding the abrasive free particles on the soft metal layer surface.
CONSTITUTION: The protective layer 6 covering the slide surface other than the gap 3 of the magnetic head consisting of the magnetic circuit 1, coil 2, magnetic gap 3, case 4, and slide surface 5 is provided by shaping a part of the slide surface 5 of the case 4. The protective layer 6 is formed by evaporating and plating the soft metal(tint and lead or the like) and finish is made so that the abrasive particles 7 can work as the free particles by using the wrapping powder or oil including the abrasive particles 7 such as diamond. Thus, in comparison with the slide contact of the magnetic tape 8 using protective layer of hard chromium, several times of wear proof can be obtained.
