Abstract
In a magnetic head comprising a magnetic core formed by joining core halves of metal magnetic material, wear-resistant films are formed on both sides of the magnetic core in such a manner that they are located at both ends of the operating gaps in the tape slide surface of the magnetic head, with non-magnetic films arranged between the magnetic core and the wear-resistant films, whereby the magnetic head is high in wear resistance and can be manufactured with high efficiency.
