A recording method for dye-based recordable DVD medium which includes recording shortest marks on a recording layer primarily containing an organic dye using a simple rectangular wave pulse; recording marks each having the second shortest or still longer mark length using one pulse of which the front and rear edges are highly energized for a given time; and controlling the optical energy for irradiating rear edge or backward of the pulse with a cooling pulse to be 0.1 mW or less for a given time, wherein when the recording power of the front and rear edges of the respective pulses is represented by P<SUB>1 </SUB>and the recording power of intermediate pulse between the pulse front edge and the pulse rear edge is represented by P<SUB>2</SUB>, P<SUB>1</SUB>/P<SUB>2 </SUB>is set to be greater when P<SUB>1 </SUB>is a low power, and P<SUB>1</SUB>/P<SUB>2 </SUB>is set to be smaller when P<SUB>1 </SUB>is a high power.
