Abstract
A method for fabrication of magnetic write heads for disk drives in which a Player is formed having a PProtrusion, the PProtrusion having a longitudinal reference axis. A gap layer is deposited on the PProtrusion and a layer of fill material is deposited on the gap layer. The fill material layer is shaped to form a mold which surrounds a hollow which is aligned with the longitudinal axis of the PProtrusion. This hollow in the fill material layer is filled with Ppole material to form a Ppole which is then automatically substantially aligned with the longitudinal axis of the PProtrusion.
