MAGNETIC RECORDING MEDIA AND PRODUCTION METHOD THEREFOR

摘要

The present invention is a production method for a magnetic recording media in which at least a magnetic layer, a protective layer, and a lubricnat layer are sequentially layered onto a non-magnetic substrate 1, and non-magnetic substrate 1 is surface treated using a gas activated by plasma generated at around atmospheric pressure. As a result of the present invention, it is possible to produce magnetic recording media with good yield that have few errors and superior head floating properties, by effectively removing foreign material and projections present on the surface of the magnetic recording media.
