Abstract:
1. A magnetic write head, comprising: a first magnetic pole; a magnetic pedestal formed over and magnetically connected with the first pole in a pole tip region, the pedestal having an air bearing surface and a back end opposite the air bearing surface; a second magnetic pole formed above the first magnetic pole and magnetically connected with the first pole by a magnetic back gap structure disposed opposite the pole tip region; an electrically conductive coil having turns passing between the first and second poles between the pedestal and the back gap structure; a non-magnetic write gap disposed between the magnetic pedestal and the second pole; a layer of photoresist material formed over the first pole, a portion of the photoresist material being disposed between the turns of the coil, and a portion of the photoresist material being disposed between the coil and the pedestal; and a layer of Al wherein the layer of alumina is partially interspersed between the turns of the coil.
