Claims

[Scope of utility model registration request]

Magnetism made of metallic magnetic material with a front gap.
A thin film made of a non-magnetic material is formed in a region including the front gap on the surface of the rad core facing the recording medium so that the film thickness is smaller than the gap length of the front gap (preferably 172 mm or less). A magnetic head.
