METHOD OF PRODUCING MAGNETIC RECORDING MEDIUM, AND MAGNETIC RECORDING AND READING DEVICE

摘要

The present invention aims to provide a method of producing a magnetic recording medium which is a method of producing a magnetic recording medium a magnetically-separated magnetic recording pattern, the method including: forming a magnetic layer on a non-magnetic substrate; then exposing a surface of the magnetic layer partially to reactive plasma, or a reactive ion generated in the plasma to amorphize the portion of the magnetic layer.
