摘要:
A magnetic head comprises a first abutting segment formed with a winding groove having an open side, and a second abutting segment opposed to the open side of the groove and joined to the first segment. The first abutting segment comprises a first core segment having the groove, and gap spacers and second ferromagnetic thin films formed on the surface thereof opposed to the second segment and positioned above and below the groove. The first core segment comprises a core segment member made of a ferromagnetic material, formed with the groove and having a first ferromagnetic thin film which is formed on the surface thereof opposed to the second abutting segment and which is positioned toward the face of the head to be opposed to recording media. The second abutting segment has a face to be opposed to the recording medium and formed by a nonmagnetic material.
