    • The object is to provide an optical recording method improving the recording characteristics and uniformity in a CAV recording on a phase-change optical recording medium, particularly a high-speed rewritable DVD medium, and a phase-change optical recording medium and an optical recording apparatus used by the method. Regarding a recording method for recording on the phase-change optical recording medium where a recording light comprises a pulse string of heating and cooling pulses, and a light for erasing, an irradiation power is controlled by peak power (Pp), bottom power (Pb) and erase power (Pe), at least any one of Pe/Pp, Pp, Pb and Pe is variable from the minimum to maximum recording linear velocities allowed for the medium, and further the irradiation time of each pulse is varied proportionally with clock T corresponding to a recording linear velocity, the present invention provides an optical recording method which performs a recording by varying at least Pe/Pp from a specific recording linear velocity lower than a peculiar recording linear velocity at which the recording linear velocity degrades abruptly showing a local maximum value, and an optical recording medium and an optical recording apparatus used by the method.
