Perpendicular magnetic write head having a hull shaped stitched pole

摘要

A magnetic write head has a stitched magnetic pole or shaping layer 308 for conducting magnetic flux to the pole tip portion 302 of a magnetic write pole. The stitched magnetic pole is recessed from the air bearing surface and has a shape so as to be thicker in a central region that is aligned with the pole tip of the write pole and is thinner at its outer sides. This shape helps to channel magnetic flux to the pole tip portion of the write pole while maintaining sufficient pole surface area for high data rate recording. The stitched magnetic pole has a trailing edge surface that is flat and the leading edge surface is convex and curved to form the thicker centre resembling the shape of a boat hull.
