Abstract

PURPOSE:To keep sharp linearity of thin film magnetic pole and to increase the durability, by making holes on the high permeability thin film, filling in adhesives to the thin film holes and bonding the both film side surfaces with the side surface member of nonmagnetic member. CONSTITUTION:The magnetic pole 1 of vertical magnetization type magnetic head is bonded with the mirror-polished nonmagnetic member (such as ferrite) provided with rectangular holes 1a or round holles 1b of stripe shape on the high permeability magnetic substance film like permalloy for the side member 3. Another side member 4 is coated with the adhesives 2 for the mirror-polished plane, and the adhesives 2 is filled in the holes 1a or 1b to clip the magnetic pole 1. Next, this three layered construction body is cut out into a given size for the formation of curved surface of tape slide surface to form barrel type. Thus, even with the thickness 1mum or less for the bonding layer between the magnetic pole 1 and the members 3, 4 the bonding strength can sufficiently be kept, and since the bonding layer is thin, the linearity of edge of the magnetic pole 1 for the sharpness can be kept. Thus, the resolution of short wave recording can sufficiently be given, which is the characteristic of the vertical magnetizing type head, and the durability can also be increased.
