ABSTRACT:
A magnetic head having a single crystal ferrite core, a magnetic gap formed in the ferrite core, a high saturation flux metal film disposed in close proximity to the magnetic gap, and a sliding surface. This sliding surface is formed on a surface of the ferrite core, and a recording medium slides thereon relative to the ferrite core in a sliding direction. The sliding surface is in the (110) plane, and the easy magnetization directions <100> of the (110) plane makes an angle equal to or greater than 20.degree. with the sliding direction. With this arrangement, the wiggle phenomenon can be effectively prevented.
