| [57] Abstract: |
| A magnetic recording media has a magnetic layer formed on a substrate and includes data regions including a magnetic pattern constituting a recoding track and servo regions including magnetic patterns used as address bits, the data regions and the servo regions being contained in a plane of the magnetic layer. In a case where two magnetic patterns used as address bits on the servo regions corresponding to two adjacent recording tracks are arranged in such a manner that one corner of one of the magnetic patterns is closest to one corner of the other, the corners of the two magnetic patterns are substantially joined together. |
