<p>PURPOSE:To form the magnetic memory medium contg. a lubricant which prevents the attraction of a head and the magnetic memory medium, is not removed by sliding with the head, is not splashed by the rotation of the magnetic memory medium and has excellent wear resistance. CONSTITUTION:This magnetic memory medium has the structure that the surface of a substrate body 1 is coated with a magnetic medium 2, further the surface of the medium is coated with a protective film 3 and the surface of the protective film is coated with the lubricating 4 having functional groups of >=110 number of inorg. groups. The magnetic memory medium has a small coefft. of friction to sliding with the head and is less changed by the sliding.</p> |
