Abstract:
1. A method for manufacturing a magnetic head comprising the steps of: (a) forming a magnetic pole layer using a magnetic material; (b) providing a first insulating layer over both sides and an upper surface of the magnetic pole layer to form a protruding portion, which covers the magnetic pole layer, and a flat portion disposed around the protruding portion; (c) laminating a second insulating layer on the flat portion of the first insulating layer; (d) laminating a third insulating layer on the first and second insulating layers; (e) polishing the third insulating layer and the protruding portion of the first insulating layer to expose the upper surface of the magnetic pole layer and so that the upper surface of the magnetic pole layer is coplanar with an upper surface of the second insulating layer; and (f) forming a coil layer above or below the magnetic pole layer.
