发明名称 Magnetic recording medium
摘要 A magnetic recording medium on which servo information is recorded efficiently with a sufficient output amplitude for favorable read accuracy of the servo information. In servo areas, a magnetic layer is separated into a plurality of servo pattern unit parts forming a predetermined servo pattern and servo pattern peripheral parts/part surrounding the servo pattern unit parts. The servo pattern unit parts and the servo pattern peripheral parts/part are formed in different sizes so as to have different magnetic properties.
