    摘要： An information recording method including irradiating a phase change recording layer of an optical recording medium with either a multi-pulse laser light train having a recording power of Pw or laser light having an erasing power Pe to allow the recording layer to reversibly achieve a crystal state and an amorphous state, thereby recording a mark having a length nT in the recording layer, wherein n is an integer of from 3 to 14 and T represents a clock cycle, wherein the multi-pulse laser light train has a constitution such that a heating pulse and a cooling pulse are alternated and the number of heating pulses and the number of cooling pulses each increases by 1 when n increases by 2, and wherein n is from 6 to 14, the last heating pulse (Br) and last cooling pulse (Cr) have a pulse width of from 0.5T to 0.9T and from 0.7T to 1.5T, respectively.
