INFORMATION RECORDING METHOD AND DEVICE

摘要

PROBLEM TO BE SOLVED: To enable a high density recording even when a relative speed between an energy beam and an information recording medium changes for information recording media having various cooling speeds. SOLUTION: This method performs information recording by irradiating an information recording medium with a recording energy beam by power modulating the beam on a high power level and an intermediate power level lower than the high power level. At this time, recording is performed by a recording waveform having a pulse downward a power level P11 lower that the intermediate power level Pm1 after a continuous high power pulse train having a power level Ph1 and the width of the downward pulse is changed according to the relative speed between the energy beam and the information recording medium.
