ABSTRACT:
A thin film magnetic head having a contact surface which, when such magnetic head is in use, slidingly contacts a magnetic information carrier, such as a magnetic tape, drum or disc, for the information recording or reproduction. The magnetic head comprises a support substrate on which a thin magnetic layer and a non-magnetic layer are deposited in side-by-side relation to each other. The non-magnetic insulating layer has a wear resistance equal to or higher than that of the thin magnetic layer. A method for the manufacture of the thin film magnetic head is also disclosed.
