摘要:
A perpendicular magnetic write head having a notched, self aligned trailing shield for canting a magnetic field emitted therefrom. The invention provides a notched trailing shield that minimizes stray field formation while improving field gradient. The write head having a notched trailing shield is extremely manufacturable, being self aligned with the write pole of the perpendicular write head and using presently existing manufacturing methods.
