PROBLEM TO BE SOLVED: To provide a magnetic recording medium suitable for efficiently forming track servo information and efficiently making a magnetic part in a user data region into an as-deposited state. SOLUTION: The magnetic recording medium X1 has a laminated structure including a base material and a recording layer 12, and the recording layer 12 includes: a plurality of information tracks 12A each having a track servo signal region TS and a user data region YD; and non-magnetic parts 12B interposed between adjacent information tracks 12A. The track servo signal region TS has a plurality of magnetic parts 12a arranged in a track extending direction and non-magnetic parts 12b interposed between adjacent magnetic parts 12a. The user data region YD has magnetic parts 12c extending in the track extending direction. Coercive force of the magnetic part 12a and coercive force of the magnetic part 12c are different from each other. For example, coercive force of the magnetic part 12c is higher than the coercive force of the magnetic part 12a. COPYRIGHT: (C)2007,JPO&INPIT
