Abstract:
A recording method for a dye-based recordable optical recording medium including recording shortest marks on a recording layer containing a dye formed on a substrate having a guide groove using one pulse beam, and recording second shortest marks or still longer marks at a pulse power as high as or lower than that of the shortest marks using one pulse beam of which two sites of the front edge and rear edge of pulse are highly energized for a given length of time, wherein a ratio Pc/W4 during recording of each mark at 12 m/s or more is set within 1.0 to 3.0; or the irradiation time of the cooling pulse Tc after that the pulse is applied with beams when the Pc/W4 ratio is 0.14 or less is set to be as long as or shorter than the basic clock cycle T.
