ツド。[Scope of Claim for Utility Model Registration] In a single magnetic pole type magnetic head having a magnetic flux return path core in the track width direction, both sides in the track width direction of a non-magnetic core that is wider than the track width of the metal ferromagnetic film main pole. A core half with a metal ferromagnetic film arranged as a return path core on its surface, and a core half with a metal ferromagnetic film main magnetic pole adhered to the track width part of a non-magnetic core are combined with the return path core and metal. The ferromagnetic film main pole is separated by a predetermined distance at least on the sliding surface with the medium,
A single magnetic pole type magnetic head, characterized in that a non-magnetic core having a width greater than the track width and a metal ferromagnetic film main pole are arranged so as to overlap each other.
