    • An optical information recording medium which makes it possible to reduce the noise level, improve the C/N ratio and store record data for a long time period. An optical information recording medium has a recording layer formed on a substrate, for having a laser beam irradiated thereto for recording and reproduction of record data. The recording layer includes a first sub-recording film and a second sub-recording film. The first sub-recording film is formed of a first material containing Si as the main component. The second sub-recording film is formed of a second material containing Al as the main component and having Ti added thereto, and disposed in the vicinity of the first recording film. The laser beam is irradiated to the recording layer via a light transmitting layer formed in a manner covering the recording layer side.
    • 一种光学信息记录介质,其可以降低噪声水平,提高C / N比并长时间存储记录数据。 光学信息记录介质具有形成在基板上的记录层,用于对其进行照射的激光束记录和再现记录数据。 记录层包括第一副记录膜和第二副记录膜。 第一副记录膜由包含Si作为主要成分的第一材料形成。 第二子记录膜由包含Al作为主要成分并且添加有Ti并且设置在第一记录膜附近的第二材料形成。 通过以覆盖记录层侧的方式形成的透光层将激光束照射到记录层。
