Magnetic recording medium and method of manufacturing 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 surrounding the servo pattern unit parts. The servo pattern unit parts and the servo pattern peripheral parts are formed in different sizes so as to have different magnetic properties. <IMAGE> |
