The method of manufacturing a magnetic recording medium having a magnetically separated magnetic recording pattern includes forming a magnetic layer on a nonmagnetic substrate, forming a mask layer made of carbon to form the magnetic recording pattern on the magnetic layer, forming cobalt carbide as a nonmagnetic material in the magnetic layer by irradiating a region of the magnetic layer not covered by the mask layer with ion beams including carbon hydride ions, and removing the mask layer in this order."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method of manufacturing magnetic recording medium and magnetic recording and reproducing device","description":"A method of manufacturing a magnetic recording medium having a magnetically separated magnetic recording pattern is provided, in which the surface of a magnetic layer is not oxidized or halogenated, t","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8486486","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.
