发明名称 Method of manufacturing a magnetic head having a relatively large air-gap and a good resistance to mechanical wear
摘要 A method of manufacturing a magnetic head, with a relatively large gap for reading, for instance, magnetic cards, and having a good resistance to mechanical wear, is provided. The head comprises two members with flat and parallel faces, made of a spinel ferrite having a high Curie temperature, encompassing a layer of non magnetic ferrite, 10 to 50 micrometers in thickness, deposited by silk-screen printing on one or both of the mutually opposite flat faces. The assembly is then bonded by sintering under pressure.
