Claims

[Scope of utility model registration request]

In the magnetic head, a second magnetic material is bonded to both sides of opposing surfaces of the first magnetic materials, and a core gap is formed by a gap between the bonded second magnetic materials. 1. A magnetic head, characterized in that a concave portion recessed from the sliding surface is formed at a joint end portion of the core where the joint surface of the magnetic medium and the second magnetic material is exposed on the sliding surface side of the magnetic medium.
