ABSTRACT:
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 P1and the recording power of intermediate pulse between the pulse front edge and the pulse rear edge is represented by P2, P1/P2is set to be greater when P1is a low power, and P1/P2is set to be smaller when P1is a high power.
