Claims

[Claims for Utility Model Registration] A pair of head halves 24, 27 are integrally joined with their gap facing surfaces via a gear spacer. A high magnetic permeability material core half body 25a having a slope inclined to one side from the center, a soft magnetic film 22 with a high saturation magnetic flux density formed on the slope of the high magnetic permeability material core half body 25a, and a gap portion. It has high hardness non-magnetic materials 21 and 23 provided on both sides in the direction perpendicular to the recording medium running direction, and when both head halves 24 and 27 are joined and integrated, the head halves 24 and 27 are Each soft magnetic film 22
2. A composite magnetic head characterized in that the soft magnetic film 22 forms a V-shape by butting side edges thereof, and a gap 28 is formed at the butting portion.
