ABSTRACT:
A perpendicular write head includes a main pole comprising a Durimide/Alumina hard mask formed over a laminate layer process to form the main pole without using a liftoff or chemical mechanical polishing process, thereby avoiding rounding corners of the pole, the main pole being controlled in shape for improved control of critical dimension of track width and angle of the bevel to avoid undesirable adjacent track writing.
