More Information
Summary:Weather resistance and lubricity of a magnetic recording medium comprising a non-magnetic support having provided thereon a vapor deposited magnetic thin film mainly composed of cobalt, nickel and oxygen can be improved by limiting the amount of nickel and the number of oxygen atoms to a specific value and by providing a plasma polymerized layer on the magnetic thin film.
