发明名称 Magnetic recording medium and method of manufacturing magnetic recording medium
摘要 A magnetic recording medium and a method of manufacturing the same which serve for stable head behavior and efficient recording of servo information. In each servo area, a magnetic layer is separated into a plurality of servo pattern unit parts for forming a predetermined servo pattern and a plurality of servo pattern gap filling parts patterned to fill gaps between the plurality of servo pattern unit parts partly. The servo pattern unit parts and the servo pattern gap filling parts are formed in different sizes so as to have different magnetic properties.
