    摘要： A magnetic transducer head in which the magnetic core elements of ferromagnetic oxides are sliced obliquely across the junction surface of the core elements, ferromagnetic metal thin films are formed on the resulting inclined surfaces by employing a physical vapor deposition, and the core elements are placed with the respective ferromagnetic metal thin films abutting to each other for defining a magnetic gap therebetween, wherein the improvement consists in that said inclined surfaces with the ferromagnetic metal thin films formed thereon are inclined at a preset angle with the magnetic gap forming surface, in that non-magnetic films having high-hardness are interposed between the ferromagnetic oxide and the ferromagnetic metal thin films, and in that said ferromagnetic metal thin films and the oxide glass fillers are provided on the tape abutment surface by the intermediary of the non-magnetic film having high-hardness.The provision of the non-magnetic film having high-hardness between the ferromagnetic oxide and the ferromagnetic metal thin film is effective to inhibit the reaction otherwise occurring between the oxide and the films, while positively preventing the formation of the boundary layer with inferior magnetic properties.Likewise, the provision of the non-magnetic film having high-hardness between the ferromagnetic metal thin film and the oxide glass is effective to prevent the erosion of the film by the molten glass, while also improving the molten glass fluidity.It should be noted that the non-magnetic films having high-hardness may be provided on the interface only between the core elements and the metal thin films or on the interface only between the metal thin films and the oxide glass.

    摘要： The formation of a gap in a magnetic head core or the junction of a thin magnetic film of a metal with an oxide substrate of a magnetic head made of a composite of a thin magnetic film of a metal with an oxide material are conducted by the thermal diffusion between gold layers themselves at a low temperature. Then, chromium or titanium is provided between the gold layer and the junction surface to prevent deterioration of magnetic characteristics and generation of a false gap and, at the same time, to heighten the junction strength. The thermal diffusion between the gold layers themselves is effected at a temperature lower than that of glass fusion to suppress the deterioration of magnetic characteristics, distortion caused by thermal expansion, and diffusion reaction on the interface. The chromium or titanium layer works to maintain function strength between the thin magnetic layer or the oxide substrate and the gold layer.
