Thermally-assisted magnetic recording method and thermally-assisted magnetic recorder

摘要

In a thermally-assisted magnetic recorder configured to heat a medium with a heat source like a light beam and thereby decrease the coercive force of a recording portion so as to magnetically record information on the recording portion decreased in coercive force by applying a recording magnetic field from a recording magnetic pole thereto, relative timing between heating of the medium and magnetic recording is optimized by locating a reversing point of magnetization, in which the coercive force of the recording portion equals the intensity of the recording magnetic field, in the leading side of the trailing edge of the recording magnetic pole.
