    摘要: A method of recording information using a laser on a multilayer optical disk having a plurality of recording layers is provided. The plurality of recording layers include a first recording layer and a second recording layer adjacent the first recording layer. The first recording layer is provided with a first test writing area to be used for calibration of write power, and the second recording layer is provided with a second test writing area to be used for calibration of write power. The disk is arranged so that a first region of the first test writing area is superposed with a second region of the second test writing area when considered in the direction in which the laser is arranged to irradiate. The method comprises, if the second region of the second test writing area is unrecorded, recording data in the second region of the second test writing area, thereby converting the second region of the second test writing area into a recorded state; and once the second region of the second test writing area has been converted into a recorded state, performing test writing in the first region of the first test writing area.

    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.
