The write head includes a substrate and a magnetic write pole formed on the substrate, the write pole having a trailing edge and first and second sides. A magnetic stitched pole is 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 walls are formed at the first and second sides of the write pole. The non-magnetic side walls 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 walls extend from the substrate to a point between the substrate and the trailing edge, allowing the stitched magnetic pole to extend partially over the sides of the write pole."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Perpendicular magnetic write head having a novel shield structure","description":"A magnetic write head for perpendicular magnetic data recording.
