ABSTRACT 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 the 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 ferro- magnetic oxide and the ferromagnetic metal thin films, and in that the 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 ferro- magnetic 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 ferro- magnetic 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 hazing 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.
