    摘要： 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.

    摘要： An optical disc having a transition linear velocity of 8-11 m/s when irradiating continuous light with 11±1 mW and a wavelength of 660±10 nm using a pickup head with a numerical aperture (NA) of 0.65, and satisfying the following condition: ΔR=|Rb—Ra|≦3% where Rb is a reflectance of an unrecorded area, and Ra is a reflectance of the top of an eye pattern after ten cycles of recording. In one recording mode therefor, the disc is rotated at a constant angular velocity so as to have a linear velocity of 3–4 m/s on an innermost track and a linear velocity of 8–9 m/s on an outermost track. In another mode, the disc is rotated at a constant angular velocity so as to have a linear velocity of 5–6 m/s on an innermost track and a linear velocity of 13–14 m/s on an outermost track.
