Abstract

A magnetic head of storage/read separation type in which both a reproducing head of magnetoresistive type and a write head of magnetic induction type are formed through a magnetic shield. The magnetic head includes a ferromagnetic material and an antiferromagnetic material in intimate contact with said ferromagnetic material. At least a part of the antiferromagnetic material acts to bring about unidirectional anisotropy in the ferromagnetic material, and is made of Cr--Mn-based alloy, and at least a part of the ferromagnetic material in intimate contact with the antiferromagnetic material is made of Co or Co-based alloy.
