Claims

[Scope of utility model registration request]

A winding groove is carved at the outflow end of a non-magnetic slider, and a magnetic core equipped with a magnetic gap made of a magnetic material around which a winding coil is wound is bonded to the slider so as to face the winding groove, and facing the recording medium. The composite magnetic head is characterized in that the magnetic core is bonded to the slider with the magnetic gap located at the same position as the deep inner wall of the winding groove or near the inflow end. Composite magnetic head.
