A magnetic recording head used for microwave-assisted recording includes: a main pole; a spin torque oscillator that is disposed on the main pole and includes a magnetization high-speed rotation layer for rotating magnetization at a high speed by a spin torque; a protective film that is disposed in the track width direction of the spin torque oscillator; an insulating film formed over the wall surfaces of the main pole and the wall surfaces of the protective film; and a magnetic film formed on the insulating film so as to cover at least the main pole."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Magnetic recording head, method of manufacturing the same, and magnetic disk unit","description":"Minute elements are formed while a photo deviation is suppressed between a spin torque oscillator and a main pole and damage is prevented on the ends of the spin torque oscillator in microwave-assiste","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8520338","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.
