Patent ID: 7461447

Claim:
A method of fabrication of a magnetic head including a read head sensor comprising: A) providing a read sensor stack having a front edge, a rear edge, a right side edge and a left side edge, said sensor stack having at least one pinning layer, at least one pinned layer and a free layer; B) milling said left side edge, said right side edge, said front edge and said rear edge of said sensor stack; C) annealing said read sensor stack in a magnetic field to set the final orientation of said pinning layer; D) encapsulating said annealed read sensor stack in overcoat material having a removal area and a front surface; E) establishing a projected final ABS boundary which lies within said overcoat material and establishing a trim range relative to said projected final ABS boundary; and F) lapping said front surface of said overcoat material until said front surface is within said trim range.
