The write pole layer may be conformal in shape to, but have smaller dimensions relative to, the main write pole, such that a distance between their outer surfaces is generally constant in a flare region. The WATER reservoir width, in a cross-track direction, may be greater than or equal to the maximum width of the main write pole."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Perpendicular magnetic recording writer having improved performance and wide area track erasure reliability","description":"A magnetic writer includes a high magnetic moment write pole layer on a main write pole, the write pole layer including a proximal end recessed from the air bearing surface, and a Wide Area Track Eras","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9779765","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.
