Abstract The thermally-assisted magnetic recording method is a method to perform information recording on a magnetic recording medium by a thermally-assisted magnetic recording head having a magnetic pole and a heating element, and the method includes: performing annealing treatment of the heating element through applying first energy to the heating element and heating the heating element; and performing information recording to a predetermined recording region of the magnetic recording medium after the annealing treatment. The information recording is performed through rotating the magnetic recording medium as well as floating the thermally-assisted magnetic recording head above the magnetic recording medium, and applying second energy to the heating element to heat a predetermined recording region of the magnetic recording medium as well as applying a write magnetic field from the magnetic pole to the predetermined recording region.
