ABSTRACT:
A thin film magnetic head is composed of a first thin film of a magnetic material deposited on a non-magnetic substrate. A V-like groove is formed in the first magnetic thin film with a depth reaching the non-magnetic substrate. One wall face of the V-like groove is deposited with a non-magnetic thin film, and the V-like groove is filled with a second magnetic thin film. A magnetic gap provided by the non-magnetic thin film is used as the magnetic head gap.
