Magnetic Recording Medium and Production Process Thereof

摘要

The present invention provides a magnetic recording medium having superior startup operation and durability as well as satisfactory surface lubricity. The present invention relates to a production process of a magnetic recording medium in which at least a magnetic layer, a protective film layer and a lubricant layer are sequentially laminated on a non-magnetic substrate, wherein the protective film layer is surface treated using a gas activated by plasma generated at a pressure in the vicinity of atmospheric pressure. The present invention also relates to a magnetic recording medium produced according to the aforementioned production process.
