ABSTRACT:
A composite magnetic material and a magnetic head made from this composite magnetic material formed of a combination of a body of a magnetic metal material and a magnetic oxide material joined together in such a manner as to provide improved strength while attaining an improved manufacturability and regenerative sensitivity at high frequencies. In accordance with the invention, the two bodies are joined together with a thin magnetic metal film initially formed on the oxide material body by vapor deposition or sputtering. The thin magnetic metal film can be made of the same material as the magnetic metal material body.
