ABSTRACT:
A wrap around shield of a write head is fabricated in multiple processes, with side shields fabricated in one process, and a trailing shield formed in another process. These multiple processes form a stitched wrap around shield, resulting in more flexible and accurate placement of the trailing shield and side shields with respect to the write pole. These processes also independently form the dimensions (shapes and sizes) of the side shields and the trailing shield which allows better control of writeability, saturation, and adjacent track interference of the perpendicular recording write head.
