Phase-change information recording medium and optical recording method to make higher rotation rates feasible

摘要：

An information recording medium includes a substrate, a first protective layer formed on the substrate, a recording layer formed on the first protective layer, and a second protective layer formed on the recording layer. The first protective layer has a thickness in a range from 65 nm to 130 nm. The second protective layer has a thickness in a range from 15 nm to 45 nm. The recording layer has a thickness in a range from 15 nm to 35 nm and is composed of a phase-change alloy with the composition in terms of atomic percentage being represented by the formula AgaInbSbcTed where 0

摘要（中）：

信息记录介质包括基板，形成在基板上的第一保护层，形成在第一保护层上的记录层和形成在记录层上的第二保护层。第一保护层的厚度在65nm至130nm的范围内。第二保护层的厚度在15nm至45nm的范围内。记录层的厚度在15nm至35nm的范围内，并且由相变合金组成，其原子百分比的组成按公式表示。信息记录介质被配置为提供读取，写入和以1.2米/秒至11.2米/秒的线性旋转速率重写信息。此外，光学记录方法适于以线性旋转速率实现信息记录介质的信息的读取，写入和重写，而不会显着降级。
