Abstract
A lubricating layer is applied to the surface of a thin protective layer on a magnetic recording medium. The surface of the protective layer is burnished to reduce protuberances. The lubricating layer is removed by solvent washing. Then, a replacement lubricating layer is deposited on the surface of the protective layer. The resulting surface of the magnetic recording medium exhibits reduced scratching and particle contamination.
