It is preferable that the lower protective layer and the upper protective layer are formed of a carbon-based material, and it is further more preferable that the lower protective layer and the upper protective layer are formed of diamond-like carbon. Moreover, it is preferable that the contact angle of the lower protective layer with respect to water in the atmosphere is 25° or less."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Manufacturing method for magnetic recording medium","description":"A manufacturing method for a magnetic recording medium which includes a magnetic layer, a lower protective layer, an upper protective layer and a lubricating layer on a substrate, and in which the tot","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9758873","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.
