    • This invention is an optical data recording medium having a substrate protective film for effectively suppressing deformation (warpage) associated with change in environmental humidity. The optical data recording medium includes a transparent substrate, a thin film layer formed on one surface of the transparent substrate, a thin film protective film formed of a resin as a main component on the thin film layer, and a substrate protective film formed of a resin as a main component on the other surface of the transparent substrate than the thin film protective film, in which the thin film layer is a single layer film or a multi-layer film including at least one of a dielectric film, a recording film and a reflective film, and the substrate protective film has a coefficient of humidity expansion that is larger than a coefficient of humidity expansion of the thin film protective film.

    • An optical information recording medium (1) includes on a substrate (50), a ROM layer (20), a RE layer (40), an intermediate layer (30) separating the ROM layer (20) and the RE layer (40), and a light transmitting layer (10) provided farthest from the substrate (50). The RE layer (40) is an information recording layer provided most farthest from the light transmitting layer (10), and is a recording layer of BCA recorded in a format easily determinable as compared to an information recording format used in the ROM layer (20), and antifouling property of a surface of the light transmitting layer (10) is set based on the RE layer (40). This makes it easy for the recording and reproducing apparatus to confirm a disc type, allows for sharing one recording and reproducing apparatus with other types of optical discs, and simplifies the disc production. Furthermore, an optical information recording medium is accomplished, in which outdated data on the ROM layer is replaced by recording, on the RE layer, updated data obtained while Internet connection can be established.
    • 光信息记录介质(1)包括在基板(50),ROM层(20),RE层(40),分离ROM层(20)和RE层(40)的中间层(30) ,以及距离基板(50)最远的透光层(10)。 RE层(40)是与光发射层(10)最距离设置的信息记录层,并且是以与在ROM层(20)中使用的信息记录格式相比容易确定的格式记录的BCA的记录层 ),并且基于RE层(40)设定透光层(10)的表面的防污性。 这使得记录和再现装置易于确认盘类型,允许与其他类型的光盘共享一个记录和再现装置,并且简化了盘的制作。 此外,在RE层上,通过记录来实现在ROM层上的过时数据被替换的光信息记录介质,可以建立互联网连接时获得的更新数据。
