Patent ID: 7716813

Claim:
A method for fabricating a magnetic recording head, comprising: A) depositing an insulation layer above a wafer surface; B) depositing a magnetic pole layer above portions of said insulation layer; C) depositing a cap layer above said magnetic pole layer; D) fabricating a resist layer above said cap layer, said resist layer being composed of a resist material that is adapted for E-beam lithography; E) removing portions of said resist layer such that a pole tip mask composed of said resist remains disposed above portions of said magnetic pole layer; F) milling said magnetic pole layer and said cap layer to form a write pole tip protrusion having write pole tip protrusion wall portions; G) depositing an alumina layer over said write pole tip protrusion to create initial alumina wall portions of said alumina layer that are disposed upon said write pole tip protrusion wall portions; H) milling said alumina layer to produce protected portions of said write pole tip having remaining alumina wall portions that are disposed over said write pole tip protrusion wall portions and unprotected portions of said magnetic pole layer; and I) milling said unprotected portions of said magnetic pole layer to form an upper portion and a beveled portion of said write pole tip, wherein sidewalls of the beveled portion taper towards one another as the sidewalls approach the insulation layer.
