METHOD OF MANUFACTURING MAGNETIC RECORDING MEDIUM AND MAGNETIC RECORDING MEDIUM

摘要

According to one embodiment, a method of manufacturing a magnetic recording medium includes forming protruded magnetic patterns on a substrate, depositing a nonmagnetic material in recesses between the magnetic patterns and on the magnetic patterns, and etching back the nonmagnetic material using an oxygen-containing etching gas while reforming a surface of the nonmagnetic material.
