The composite shield has a first layer made of an isotropic magnetic material adjoining the write gap, and the anisotropic (−Ku) layer adjoins the first trailing shield layer on a side opposite the write gap. The main pole may have a tapered leading side and a tapered trailing side with the anisotropic (−Ku) leading shield and trailing shield layers extending a greater distance from the ABS than the ends of the tapered main pole sides. Adjacent track erasure is minimized while on-track write field and field gradient are improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Superior performance head design with minimized ATE and WATE","description":"A PMR writer is disclosed with an all wrap around design wherein the leading shield, side shields, and composite trailing shield are comprised of an anisotropic (−Ku) magnetic layer, and where the lea","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8498079","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
