PURPOSE:To improve abrasion resistance, a Q-characteristics, and a high frequency characteristics, by butting a pair of magnetic core half bodies so as to face oppositely metallic magnetic materials with each other, or a nonmagnetic material and an oxide magnetic material with each other, joining them in one body, and making a metallic magnetic film incline against a reference plane. CONSTITUTION:In a magnetic core main body 30, a pair of magnetic core half bodies in which the metallic films 33 and 33' are sandwiched by the nonmagnetic materials 32 and 32' made of the oxide magnetic materials 34 and 34' and crystallized glass or ceramics, etc., are butted so that the metallic magnetic films 33 and 33', and the oxide magnetic materials 34 and 34' and the nonmagnetic materials 32' and 32, are opposed with each other. Thereby, a track width can be decided by the thickness of the metallic magnetic films 33 and 33'. Also, the metallic magnetic films 33 and 33' are inclined by azimuth thetaagainst the reference plane 30 of the magnetic core main body 30. Therefore,it is possible to constitute the large part of a tape sliding plane 37 with the oxide magnetic materials 34 and 34'. In such way, a composite type magnetic head with fed deviated abrasion, and superior abrasion resistance, and with superior Q-characteristics and frequency characteristics.
