    摘要: To obtain an optical recording medium capable of recording at various recording transfer rates from a low speed to a high speed, by using a simple recording strategy. A recording layer 18 of a write-once optical recording medium capable of recording from a low speed to a high speed is formed by laminating a first sub recording layer 18A and a second sub recording layer 18B each containing a metal as its main component. When the recording layer (laminated recording layer) 18 is irradiated with a laser beam having a wavelength equal to or shorter than a blue wavelength by using a recording strategy comprising only a ratio of write power to bias power, the main component metals contained in the first and second sub recording layers 18A, 18B diffuse and are thus mixed together, forming the sub recording layers into a single layer by means of such mixing and forming recording marks whose reflectance have been irreversibly changed. Since the recording mark formation process does not need to select a recording strategy, it is possible to obtain many subordinate advantages such as a variable speed recording.

    摘要: An optical recording medium includes an optical recording layer, a separating layer formed on a reproducing light incident side of the optical recording layer, and a phase-change reproducing layer formed on the reproducing light incident side of the separating layer, absorbance of which phase-change reproducing layer is changed depending on whether a state of the optical recording layer is a recording mark or a space. A transfer portion to which a state of the optical recording layer is transferred is formed in a portion having high absorbance of the phase-change reproducing layer by irradiation with reproducing light, while a portion of the phase-change reproducing layer other than the transfer portion is kept in a state optically differing from the transfer portion.
