Claims

[Scope of utility model registration request]

A metal magnetic thin film and a high magnetic permeability oxide magnetic material are bonded together, the metal magnetic thin film forms an i-gap, and the high magnetic permeability oxide magnetic material has a notch formed in the vicinity of the magnetic gap. In the magnetic head, the magnetic gap is provided with a predetermined azimuth angle, and the end surfaces of the notches of the high permeability oxide magnetic material all have an inclination in the opposite direction to the azimuth angle of the magnetic gap. Features a magnetic head.
