Magnetic transducer head having an alloy thin film of high saturation magnetic flux density slantly provided with respect to an operating magnetic gap formed therein

摘要

A magnetic transducer head comprising a first magnetic core element and a second magnetic core element, each of the first and second core elements comprising a magnetic ferrite block and a magnetic metal thin film integrated with the magnetic ferrite block. These core elements having a first planar surface and a second planar surface. The magnetic metal thin film being provided on the second planar surface and having an edge thereof facing to the first planar surface, and the second planar surface being slantly provided with respect to said first planar surface. These core elements being bonded together to form an operating magnetic gap between the edge of the magnetic metal thin film on the first core element and the edge of the magnetic metal thin film on the second core element. The magnetic metal thin film on the first core element or the magnetic thin film on the second core element is formed in one common plane. The magnetic metal thin film may be formed of the ferromagnetic metals including Fe-Al-Si alloys, amorphous metal alloys or permalloy. And the magnetic metal thin film having substantially uniform columnar grain structure or uniform magnetic anisotropy, over entire area of the film.
