an optical recording medium is provided , the optical recording medium including a plurality of zones configured to store data corresponding to an adaptive write pulse , the adaptive write pulse including a first pulse , a last pulse , and a multi - pulse train , the adaptive write pulse being different for each of the plurality of zones , the plurality of zones being reflected by a grouping table , the grouping table being configured to generate an adaptive write pulse waveform by varying a position of a rising edge of a first pulse of a mark to be written according to a length of the mark to be written and a leading space , the adaptive write pulse waveform being generated without regard for a trailing space of a present mark being written using the adaptive write pulse waveform , the adaptive write pulse being configured to correspond to the adaptive write pulse waveform , and store rising edge data of the first pulse of the adaptive write pulse waveform varying according to corresponding stored values of lengths of marks to be written . a width of the first pulse is varied by varying the position of the rising edge .
