METHOD FOR PRODUCING MAGNETIC RECORDING MEDIUM AND PROTECTIVE FILM THEREOF |
摘要 |
<p>A method for producing a protective film for a magnetic recording medium comprises steps of (a) providing a magnetic layer formed on a substrate; and (b) forming a protective film on the magnetic layer by means of a plasma CVD method using mixed gas of specific lower saturated hydrocarbon gas and specific lower unsaturated hydrocarbon gas as source gas. Step (b) includes (b-1) of forming a first protective film on the magnetic layer and (b-2) of forming a second protective film on the first protective film. B-1 uses source gas with gas mixture ratio such that average number of hydrogen atoms per carbon atom in the source gas is greater than 2.5 but less than 3.0. B-2 uses source gas with gas mixture ratio such that the average number of hydrogen atoms per carbon atom in the source gas is greater than 2.0 but less than 2.5.</p> |
