发明名称 Method of making a magnetic head with ferrite between nonmagnetic portions and a nonmagnetic gap
摘要 A method for making a magnetic head formed with a pair of magnetic core halves fitted to abut on each other having a nonmagnetic gap therebetween and having a slide contact plane for slide contact with a magnetic recording medium on which an end face of the nonmagnetic gap and the magnetic core halves. In the method, a nonmagnetic portion formed by filling a glass material is provided at an end portion of the slide contact plane other than the end face of the magnetic core halves on the slide contact plane.
