Zusammenfassung:PROBLEM TO BE SOLVED: To record a mark without distortion within a wide line speed range in the case of recording data in an optical information recording medium. SOLUTION: A recording pulse 13 is formed so that the length of a mark 604 corresponds to the recording code length of data as a recording pulse train corresponding to a plurality of power levels including recording power and erasing power and the recording pulse train is constituted of a plurality of pulses including a multi-pulse 602 and a rear end pulse 603. Laser light is irradiated on the recording medium, and the mark is formed with a plurality of kinds of line speed. When line speed v1 and v2 are in relation of v1
