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.

摘要： In a phase change optical recording medium, by determining heat conductivity relatively higher in one of interference layers on and under the recording layer, heat absorbed into the recording layer can be released moderately through an interference layer. Thereby, cross erasure caused by heating of adjacent tracks can be prevented, and at the same time, excessive heat radiation is prevented from a part of the recording layer nearer to the substrate to thereby maintain appropriate heat in the recording layer. As a result, cross-erasure is prevented, and data can be rewritten with the supply of typical recording/erasure power.
摘要翻译： 在相变光记录介质中，通过在记录层上和下方的干涉层之一中确定相对较高的热导率，可以通过干涉层适度释放吸收到记录层中的热量。 因此，可以防止由相邻轨道的加热引起的交叉擦除，并且同时，防止来自更靠近基板的记录层的一部分的过多的热辐射，从而在记录层中保持适当的热量。 结果，防止交叉擦除，并且可以通过提供典型的记录/擦除功率来重写数据。
