A thickness of the main pole is increased in a depth direction from an air bearing surface using an inclination, and a thickness of the first nonmagnetic film increases in the depth direction from the air bearing surface. In another embodiment, an angle from a horizontal plane of an upper surface of the first nonmagnetic film is greater than an angle from a horizontal plane of a lower surface of the first nonmagnetic film in contact with the main pole. Other heads, methods, and systems are described according to more embodiments."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetic head for perpendicular recording","description":"According to one embodiment, a magnetic head for perpendicular recording includes a main pole, a first soft magnetic film disposed on a trailing side of the main pole, and a first nonmagnetic film int","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8537493","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.
