ABSTRACT:
A floating magnetic head comprises a pair of magnetic core pieces which face each other through a gap and a metal magnetic film formed on the surface facing the gap of one of the pair of magnetic core pieces. The pair of magnetic core pieces are made of a single crystal Mn-Zn ferrite, a plane of the magnetic core pieces being formed almost in parallel with the surface forming a main magnetic path, and a <100> direction in the plane being formed to meet a relation of an angle .theta. to be 26.degree.<.theta..ltoreq.45.degree. between the <100> direction and the surface facing the gap.
