发明名称 MAGNETIC HEAD
摘要 PURPOSE:To suppress the generation of contour effect without thickening a film thickness even when a track width is enlarged by extending a high saturation magnetic flux density film along the border of the one of a pair of non- magnetic parts contacting to the both edges of a magnetic gap member in a medium sliding surface and a high permeability member. CONSTITUTION:Near a gap part 3, in a magnetic head constituted by confronting core halves, magnetism alloy films 2 and 2' form border lines L1 and L3 parallel with the gap 3 between ferrites 1 and 1' on a medium sliding surface S2 and extend border surfaces S3 and S3' along the interval of the ferrites 1 and 1' in channels 5 and 5' to determine a track width. Since the border surface S1 of the magnetic alloy film 2 and the ferrite 1 in a winding window 4 crosses with the sliding surface S2 as a plane non-parallel with the forming surface of the gap 3 and forms a straight line L1, the generation of the contour effect can be relieved. Thus, a cost-down can be obtained and the track width can be arbitrarily set.
