Abstract:
A magnetic head assembly comprising:a first pole piece; a pedestal of ferromagnetic material on on end of the first pole piece; a back flux closure of ferromagnetic material on the first pole pice across from the pedestal; a layer of coils comprising a plurality of oops of conductive material on top of the first pole piece between the pedestal and the back flux closure; a hard baked photo-resist material between the pedestal, each coil loop and the back flux closure, wherein the thickness of the photo-resist material relative the coil thickness is reduced; a filler between the coil loops on top of the reduced thickness hard baked photo resist material, wherein the pedestal, back flux closure and coils, having the hard baked photo-resist material and filler between each coil loop, are planarized; and a write gap layer of non-magnetic material on top of the filler.
