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.
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, wherein:
A manufacturing method of 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, comprising the steps of:
The manufacturing method of a magnetic head according to claim 8, wherein a surface roughness of a side plane of the groove is 50 nm or less.
