Abstract
A thermally assisted magnetic recording method includes the following steps. The recording layer of a magnetic recording medium is irradiated with a laser beam to produce a locally heated region. This heated region is moved by causing the recording layer and the laser beam to move relative to each other. To record desired information, a recording magnetic field is applied to the heated region of the recording layer. The laser beam has a cross section elongated in the direction in which the heated region is moved.
