Latest Patents

One of his latest patents is titled "Perpendicular magnetic write head having a novel shield structure." This invention focuses on a magnetic write head designed for perpendicular magnetic data recording. The write head comprises a substrate and a magnetic write pole formed on the substrate, featuring a trailing edge and first and second sides. A magnetic stitched pole is positioned over a portion of the magnetic write pole, with its front edge defining a secondary flare point. The design includes first and second non-magnetic side walls that extend from the substrate to the trailing edge of the write pole, allowing the stitched magnetic pole to extend partially over the sides of the write pole.

Another significant patent is the "Method for manufacturing a perpendicular magnetic write head." This method outlines the process of creating a magnetic write head for perpendicular magnetic recording. It involves forming a write pole, depositing a refill layer, and creating a mask structure over the write pole and refill layer. The mask structure is designed to define a stitched pole, followed by ion milling or reactive ion milling to remove unprotected portions of the refill layer. Finally, a magnetic material is deposited to form a stitched write pole that aligns accurately with an electrical lapping guide.
