    • An optical information recording medium which is capable of performing high-density recording of record data, and storing the recorded data for a long time period such that the recorded data can be normally reproduced during the 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 Cu as the main component and having Zn added thereto, and disposed in the vicinity of the first recording film.
    • 一种光信息记录介质,其能够执行高密度记录记录数据,并且将记录数据长时间地存储,使得可以在长时间段内正常再现所记录的数据。 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Cu作为主要成分并且添加有Zn并且设置在第一记录膜附近的第二材料形成。
