摘要：
According to one embodiment, a method of manufacturing a discrete track recording medium includes forming protruded magnetic patterns on a substrate, and repeating processes of depositing a nonmagnetic material so as to be filled in recesses between the magnetic patterns and etching back the nonmagnetic material two or more times with rotating the substrate in a plane thereof by an angle less than one revolution.
