ABSTRACT:
A process for forming the write pole of a PMR head is described. This write pole is symmetrically located relative to its side shields, This is accomplished, not through optical alignment, but by coating the pole with a uniform layer of non-magnetic material of a predetermined and precise thickness, followed by the formation of the shield layer around this.
