• The comparison between the dual gradient recording method (DGRM) and the thermal gradient recording method (TGRM) for thermally assisted magnetic recording (TAR) were investigated using the Landau-Lifshitz-Gilbert equation, which adds a stochastic thermal field to an effective field. The magnetization patterns and read/write characteristics were discussed. It was clarified that the write performance of DGRM was superior to TGRM for achieving a high areal recording density.
