Abstract:
1. A magnetic write head for perpendicular magnetic data recording, the write head comprising: a substrate; a magnetic write pole formed on the substrate, the write pole having a trailing edge and first and second sides; and a magnetic stitched pole formed over a portion of the magnetic write pole, the stitched pole having a front edge that defines a secondary flare point; first and second non-magnetic side gap layers formed at the first and second sides of the write pole; wherein the non-magnetic side gap layers extend from the substrate at least to the trailing edge of the write pole in a first region near an air bearing surface and wherein the first and second non-magnetic side gap layers extend from the substrate to a point between the substrate and the trailing edge in a second region, allowing the stitched magnetic pole to extend partially over the sides of the write pole.
