摘要:
An optical recording medium includes a support substrate, a first resin layer and a second resin layer formed on opposite surface sides of the support substrate, an information recording layer formed between the first resin layer and the support substrate and containing a recording film, and a moisture-proof layer formed between the second resin layer and the support substrate and the moisture-proof layer contains at least one element among elements contained in the recording film. According to the present invention, since the first resin layer is formed on the moisture-proof layer containing at least one element among elements contained in the recording film, on the information recording layer and the second resin layer is formed on the moisture-proof layer, it is possible to form the first resin layer and the second resin layer having substantially the same physical properties on the opposite sides of the support substrate and it is therefore possible to suppress the warpage of the optical recording medium due to heat and moisture to the minimum.
