Abstract:
A magnetic write head having a shield structure that provides both a leading shield and side shielding function. The magnetic shield is separated from the sides and leading edge of the write pole by a non-magnetic gap layer that has a non-uniform thickness. The non-magnetic gap layer is thicker near the leading edge and thinner at the trailing edge. This allows for increased side field gradient near the trailing edge of the write pole and decreased write field loss at the leading edge of the write pole.
