    摘要: A method and apparatus for initializing optical recording media is provided that detects the intensity of a reflective light off of an optical recording media and analyzes the initializing condition based on the detected intensity during an initializing process. The light is radiated on a rotating phase-change optical recording medium. The light may be moved in a radial direction of the optical recording medium. The detected intensity of the reflected light may be used to identify crystallized portions and amorphous portions of the optical media. The initialization process can be adaptively controlled to ensure proper initialization. If desired, re-initialization can be limited to those areas detected to be outside of the predetermined parameters.

    摘要: An object is to provide an optical recording medium which can obtain a sufficient focusing characteristic even at recording speeds at which a recording linear velocity exceeds 4× speed at the same capacity as a DVD-ROM, and which can suppress in-plane fluctuations of the degree of modulation, and which enables highly reliable recording, and a method of manufacturing the optical recording medium and a recording and reproducing method. To this end, there is provided an optical recording medium having a substrate, and at least a recording layer and a reflective layer on the substrate, wherein the optical recording medium is formed such that the substrate has a set central value of a thickness, and when there is a substrate thickness within a given range from the set central value, an axial direction acceleration of the optical recording medium has a maximum allowable value, and as an amount of deviation from the set central value exceeds the given range, a maximum allowable value of the axial direction acceleration at the optical recording medium becomes smaller.

    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.
