Provided by the present invention is a method for recording on a phase-change optical information recording medium including irradiating “m” number of heating pulse with power Pw and “m” number of cooling pulse with power Pc when recording a mark of n˜Tw time length, and changing a preset value of at least any one of “m”th heating pulse THm and “m”th cooling pulse TCm when “n” is voluntary during test recording and information recording when setting an optimum write power, wherein “m” is a natural number, “n” is a natural number, Tw is a channel bit length and Pw is larger than Pc, and n=2m+1 is true when “n” is an odd number and n=2m is true when “n” is an even number.
