Abstract:
A method of manufacturing a thin-film magnetic head, comprising the steps of:forming, on a lower auxiliary pole, a three-layer pole tip structure consisting of a lower pole tip element, a recording gap layer and an upper pole tip element; depositing a lower insulating layer on said three-layer pole tip structure such that the top of the three-layer pole tip structure is fully buried by said lower insulating layer; polishing said lower insulating layer by chemical-mechanical polishing so that a top surface of said lower insulating layer is leveled lower than the top of said three-layer pole tip structure over a least a region within which a coil conductor is to be formed; forming the coil conductor on said lower insulating layer; forming an upper insulating layer to cover said coil conductor; and forming an upper auxiliary pole so that a part of which contacts to said upper pole tip element.
