Abstract

PURPOSE:To manufacture a magnetic head having an azimuth angle and also a stable working gap which is free from shift of a track, by making the junction surface of a nonmagnetic material and a magnetic material orthogonal to the working gap, and also inclining this junction surface to the direction of a tape by the azimuth angle of the working gap. CONSTITUTION:A magnetic head block is prepared so that a working gap 5 is made orthogonal to junction surfaces 7a, 7b of sendast thin films 2a, 2b and nonmagnetic materials 4a, 4b, and the junction surfaces 7a, 7b coincide with the moving direction T-T' of a tape. Subsequantly, the magnetic head block 8 is mounted on a cutting jig 9 whose upper surface has been inclined by an azimuth angle theta against the bottom surface, and the magnetic head block 8 is cut by surfaces A-A', B-B' being in parallel with the bottom surface of the cutting jig 9, by which a magnetic head is obtained. This magnetic head becomes a magneric head provided with an azimuth, which has a stable working gap 5 free from shift to a track.
