发明名称 COMPOSITE TYPE MAGNETIC HEAD AND MANUFACTURING METHOD THEREOF
摘要 A composite type magnetic head comprises first and second magnetic head core halves made of a magnetic ferrite, a gap member interposed between the first and second magnetic head core halves, a first narrowed part which is formed on the first magnetic head core half and is narrowed toward the gap member by being defined by first and second curved depressions, a second narrowed part which is formed on the second magnetic head core half and is narrowed toward the gap member by being defined by third and fourth curved depressions, a first film made of a magnetic metal material formed on a surface of the first curved depression, and a second film made of the magnetic metal material formed on a surface of the third curved depression. The first and second films have film thicknesses equal to a desired track width at a part where the first and second films make contact with the gap member and form a gap of the magnetic head.
