Claims

[Scope of utility model registration request]

In a magnetic head in which a predetermined erasing gap is formed between a recording/reproducing core and an erasing core, at least one groove is provided on the surface of the distal end of the erasing core that contacts the magnetic recording medium, and the groove is provided with at least one groove. A magnetic head characterized by being filled with a non-magnetic connecting material.
