Magnetic recording medium and process for producing same |
摘要 |
A magnetic recording medium excellent in corrosion resistance and rubbing reliability is realized by forming a number of concavities and convexities on the surface of a protective layer formed on a substrate and applying dry etching with a noble gas after the formation of the concavities and convexities to form a modified layer having hydrophobic nature on the surface of the protective layer.
