<P>PROBLEM TO BE SOLVED: To provide an information recording method which allows optical information having a recording mark length smaller than a spot diameter of laser light to be recorded on an optical recording medium having a recording layer, at high density by laser light pulse application. <P>SOLUTION: The information recording method has: a power calibration step of determining a recording power for recording a signal having a predetermined signal length in the recording layer using the laser beam; and a complementing step of complementing, based on the recording power determined in the power calibration step, a recording power for recording a signal having a signal length equal to or less than 1/2 of the spot diameter of the laser beam in the recording layer using the laser beam. In the information recording method, for example, an extremely small mark, such as a 2T signal, is accurately formed. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
