ABSTRACT:
A heat-assisted magnetic recording method is provided for implementing information recording on a recording magnetic film of a magnetic recording medium rotated around a rotation center. The method includes the steps of: illuminating a recording region in the magnetic film with a laser beam for locally heating the recording region; and applying a recording magnetic field to the heated recording region. The power of the laser beam illuminating the recording region is selected in accordance with the distance between the rotation center and the recording region.
