Abstract:
1. A method of forming a write pole, comprising: applying a layer of non-conductive material onto a surface of a wafer; forming a bevel by removing a portion of the layer of non-conductive material; depositing a first layer of conductive material onto the beveled portion of the layer of non-conductive material so that part of the first layer of conductive material includes a wedge shape above a surface of the layer of non-conductive material, wherein the wedge includes a first inclined surface and a second inclined surface that is opposite the first inclined surface, and wherein the first inclined surface of the wedge and the second inclined surface of the wedge meet at a junction; and depositing a second layer of conductive material onto the layer of non-conductive material including the portion of the layer of non-conductive material onto which the first layer of conductive material is deposited.
