摘要： An information recording method 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. 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 light; 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 ½ of the spot diameter of the laser light in the recording layer using the laser light. In the information recording method, for example, an extremely small mark, such as a 2T signal, can be precisely formed.
