Abstract: There is provided 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 magnetic head, a nonmagnetic portion formed by filling a glass material is provided at an end portion of the slide contact plane outer than the end face of the magnetic core halves on the slide contact plane. The inventive magnetic head realizes less volume of magnetic body while solving problems in mechanical strength of the magnetic head or in compatibility to a conventional head. Accordingly, a magnetic head with excellent head performance without decreasing productivity can be obtained.

Abstract: A head height adjustment method is for adjusting the height of a magnetic head chip fixed to a free end of an elongated head base extending from a rotary drum. The elongated head base has an intermediate portion bent at first and second restricted areas. A laser beam is emitted on one surface of the elongated head base for bending the elongated head base at the first restricted area to enfold along the first restricted area. Another laser beam is emitted on another surface of the elongated head base, off alignment from said first restricted area, for bending the elongated head base at the second restricted area to enfold along the second restricted area. Thus, opposite end portions of the elongated head base extend parallel to each other, but at different levels.
