Patent ID: 7881011

Claim:
A magnetic write head for perpendicular magnetic recording, comprising: a substrate; a magnetic write pole formed on the substrate, the magnetic write pole having first and second laterally opposed sides and having a trailing edge and a leading edge each extending between the first and second laterally opposed sides; wherein the substrate has outward extending portions extending beyond the write pole, and wherein the outward extending portions taper in a leading direction as they extend outward from the write pole; a non-magnetic refill layer formed over the outward extending portions of the substrate and extending laterally outward from the first and second sides of the write pole, the non-magnetic refill layer having a surface plane that extends at least to the trailing edge of the write pole and having first and second transition portions adjacent to the first and second sides of the write pole that extend beyond the trailing edge of the write pole; wherein the surface plane of the refill layer is coplanar with the trailing edge of the write pole.
