ABSTRACT:
An information recording method is provided, which comprises the steps of (a) determining a power level of a pulse sequence, (b) generating the pulse sequence based on the power level determined, and (c) irradiating an information recording medium with light corresponding to the pulse sequence generated to record information represented by at least either a recording mark or a space onto the information recording medium. The pulse sequence comprises a multi-pulse chain for forming the recording mark. The multi-pulse chain comprises a plurality of pulses having a peak power level. In the step (a), a bottom power level is determined between the peak power level and an erase power level which is lower than the peak power level while keeping an interpulse spacing constant.
