<p>A method of forming a top pole member (26) in a magnetic recording head having a bottom pole member (24), an insulating layer (36) on said bottom pole member, and a shared pole member (32) over the bottom pole member on a ceramic substrate comprises the steps of: depositing a ferromagnetic material on the shared pole portion forming a shared pole tip; mechanically forming a planar insulating layer surface over the shared pole member exposing the shared pole tip flush with said planar surface; recessing the pole tip below said planar surface; depositing a gap layer (42) over the planar surface of the insulating layer and the recessed pole tip, the top pole member then being deposited into and over the channel over the recessed pole tipe. The top pole is automatically centered and aligned with the shared pole tip without ion beam milling.</p> |
