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： A magnetic transducer head wherein confronting surfaces of a pair of magnetic core parts comprised of a ferromagnetic oxide material are notched, and the notch defining surfaces have metallic ferromagnetic layers supported thereby. The method of physical vapor deposition as known per se is used for forming these layers. The transducer coupling gap of each magnetic head is defined by an aligned pair of pole piece layers formed from the deposited metallic ferromagnetic material. The pole piece layers are inclined at a preset angle with respect to the plane of the coupling gap, and have extensions formed of the deposited metallic ferromagnetic material presenting bend contours between the pole piece layers and the lateral sides of the core parts.

摘要： Each of a pair of magnetic core halves includes a substrate and a thin magnetic metal film formed on the substrate. The substrate is notched with a winding groove. The pair of the magnetic core halves are integrally bonded to each other so that a gap filling film is formed between the facing surfaces of the thin magnetic metal films. The zero depth position of the magnetic gap which is determined by the length of the facing thin magnetic metal films is offset to a magnetic recording medium sliding surface of the magnetic head from the notching start position of the winding groove on the side of the magnetic gap. Hence, the shape of the thin magnetic metal film exposed on the magnetic recording medium sliding surface is maintained constant from the initial position to the depth zero position.
