Patent ID: 8477453

Claim:
A PMR write head with a main pole layer having a planar top surface, and a planar bottom surface that is formed parallel to said planar top surface and connected to an air bearing surface (ABS) by a tapered leading side, said main pole layer comprises: (a) a pole tip portion, comprising: (1) a pole tip formed along the ABS and having a leading edge where the tapered leading side terminates, and a trailing edge at the ABS and located a pole tip thickness from the leading edge and having a track width in a cross-track direction; (2) a top surface that is part of the main pole planar top surface and extends from said trailing edge to a first plane that is parallel to the ABS and is formed a neck height distance from the ABS; (3) two sides that are separated by a track width distance along the top surface, and connect the top surface to a bottom surface; and (4) a bottom surface with a first section formed along the tapered leading side between the ABS and a main pole surface that is aligned parallel to said planar top surface and has a front edge formed a first distance from the ABS, and a second section that is coplanar with said main pole surface and extends from the tapered leading side to said first plane; (b) the main pole surface adjoining the second section of the bottom surface on each side of the pole tip portion wherein the front edge extends a second distance from a side of the pole tip portion in a cross-track direction to a long side that extends from the front edge in a direction perpendicular to the ABS to a second plane formed on an opposite side of the first plane with respect to the ABS, said second plane is parallel to the first plane; and (c) a side of the main pole layer formed between the main pole surface and planar top surface, and between the first plane and the second plane.
