Heat-assisted magnetic recording method and test record reproduction method

1. A heat-assisted magnetic recording method for implementing information recording on a recording magnetic film of a magnetic recording medium rotated around a rotation center, the method comprising:

illuminating a plurality of recording regions in the magnetic film with a laser beam for locally heating each of the recording regions; and

applying a recording magnetic field to each of the heated recording regions;

wherein the laser beam illuminating the recording regions is varied in power in accordance with a distance that varies between the rotation center and each of the recording regions; and

wherein each of the recording regions comprises a plurality of recording tracks, the laser beam illuminating the plurality of recording tracks in each same recording region is kept constant in power.

2. The heat-assisted magnetic recording method according to claim 1 , wherein the recording magnetic film comprises a plurality of concentric annulus regions having a common center coinciding with the rotation center, and wherein the power of the laser beam is selected depending on which annulus region the recording region belongs to.

3. The heat-assisted magnetic recording method according to claim 2 , wherein the plurality of concentric annulus regions include a first annulus region and a second annulus region that is farther from the rotation center than the first annulus region is, and wherein the power of the laser beam is lower for illuminating the first annulus region than for illuminating the second annulus region.
