Abstract:
1. A method of manufacturing a thin film magnetic head comprising: providing first and second magnetic layers magnetically coupled to each other and having first and second pole tip portions placed so as to face a recording medium in conjunction with being in contact with a gap layer and being opposed to each other as sandwiching the gap layer; providing a thin film coil disposed in a space between the first and second magnetic layers; and providing a first insulating layer, sandwiched between a second and a third insulating layer, embedding the thin film coil in the space between the first and second magnetic layers, wherein the method further comprises: forming the gap layer with a non-magnetic conductive material over at least the first insulating layer; forming at least the first pole tip portion on the gap layer by growing a plating film with the gap layer used as an electrode and wherein the first magnetic layer including the first pole tip portion is formed of the plating film as a single layer; and providing a trim structure comprising a portion of the first magnetic layer and a portion of the second magnetic layer in direct contact with a portion of the gap layer.
