Claims

[Scope of utility model registration request]

In a magnetic head that integrates a recording/reproducing head and an erasing head that forms erasing tracks on both sides of tracks recorded by the recording/reproducing head, a part of the core of the erasing head surrounds an expelling magnetic path. A magnetic head characterized in that a short ring made of a conductive material is inserted.
