ABSTRACT:
In a magnetic head having a pair of magnetic cores defining a magnetic gap in-between, a side of each magnetic core facing a recording medium is formed of a single-crystal ferrite, with the remaining portions of each magnetic core being formed of poly-crystal ferrite. The surface of the magnetic core facing the recording medium and the abutment surface of the magnetic core are the {100} plane and the {100} plane of the single-crystal ferrite, respectively. The magnetic head has excellent abrasion resistance and electro-magnetic conversion characteristics.
