    摘要： 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.

    摘要： An information recording method capable of properly forming a width of a central portion of a recording mark, an information recording apparatus and an information recording medium are provided. The present invention includes the steps of generating a pulse train including a first pulse and a second pulse and forming at least one of a recording mark and a space onto an information recording medium by irradiating the pulse train onto the information recording medium while rotating the information recording medium at a certain linear velocity. The first pulse is a pulse for forming a central portion of the recording mark, among the recording mark and the space. The second pulse is a pulse for forming a portion other than the central portion of the recording mark, among the recording mark and the space. The step of generating the pulse train includes a step of determining a power level of the first pulse in accordance with the linear velocity and a power level of the second pulse.
