PURPOSE:To stabilize the contact of a magnetic head with a recording medium and to extend the life thereof against wear by sandwiching and reinforcing both ends of a pair of thin soft magnetic apply films constituting a head core in the direction where the recording medium travels by and with the 1st nonmagnetic materials and sandwiching the film thickness direction thereof with the 2nd magnetic materials. CONSTITUTION:The ends on one side of a pair of the thin soft magnetic alloy films 2a, 2b to form the magnetic core are butted to form a magnetic tap and the ends on the other side are sandwiched by the 1st non-magnetic materials 4a, 4b having the wear resistance approximately equal to or better than the wear resistance of the thin soft magnetic alloy films. The overall length of a pair of the thin soft magnetic calloy films to be exposed to the sliding surface of the recording medium in the sliding direction is made 10-300mum. The thin soft magnetic alloy films and the 1st non-magnetic material are sandwiched by the 2nd non-magnetic materials 1a, 1b having the easier tendency to wear than the 1st non-magnetic materials in the film thickness direction thereof. The contact with the recording medium is thereby stabilized and the life against the wear is extended. |
