PURPOSE:To provide the titled head having excellent wear resistance by butting and integrally joining a pair of magnetic core half bodies which sandwich magnetic metallic films by nonmagnetic materials consisting of crystallized glass and oxide magnetic materials in such a manner that the magnetic metallic films as well as the nonmagnetic materials and the oxide magnetic materials face each other. CONSTITUTION:This magnetic core body 30 is formed by butting a pair of the magnetic core half bodies which sandwich the magnetic metallic films 33, 33' by the oxide magnetic materials 34, 34' and the nonmagnetic materials 32, 32' consisting of the crystallized glass or ceramics, etc., in such a manner that the magnetic metallic films 33, 33' as well as the oxide magnetic materials 34, 34' and the nonmagnetic materials 32, 32' face each other and, therefore, the track width is determined by the thickness of the films 33, 33'. The surface to slide with a tape is provided with the nonmagnetic materials 32, 32' and the oxide magnetic materials 34, 34' on both sides of a magnetic gap 36 except the films 33, 33' in a symmetrical position relation so that the surface approximate to the surface of the materials 32, 32' is easily selected. The composite type magnetic head which has high wear resistance and decreases uneven wear is thus obtd.
