Thin film magnetic head

Abstract

A thin film magnetic head fabricated in accordance with a thin film manufacturing method comprising a front end of an upper core layer formed on a magnetic gap layer, and a rear end of the upper core layer formed on an interlayer insulating layer for insulating a conductor coil layer to be coupled with the front end of the upper core layer, and a method for manufacturing a thin film magnetic head fabricated by a thin film manufacturing method comprising the steps of forming a lower core layer on a substrate made of a nonmagnetic material, forming a magnetic gap layer on the lower core layer, forming a front end of an upper core layer on the magnetic gap layer, forming an interlayer insulating layer and a conductor coil layer on the magnetic gap layer, and forming a rear end of the upper core layer coupled with the front end of the upper core layer and the lower core layer on the interlayer insulating layer for insulating the conductor coil layer. Thus, this thin film magnetic head does not cause a magnetic gap layer from being deteriorated in its characteristics by separating an upper core layer into front and rear ends and forming the front end of the upper core layer subsequently to the forming of the magnetic gap layer.
