    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.

    摘要： A disc-shaped recording medium manufacturing method includes coating an energy beam curing resin over an inner peripheral portion of a first information layer formed on a disc-shaped substrate, disposing a stamper member to face the disc-shaped substrate, rotating the disc-shaped substrate to spin-coat the energy beam curing resin, irradiating the energy beam curing resin with an energy beam while rotating the disc-shaped substrate, removing the stamper member to leave a spacer layer made on the energy beam curing resin, forming a second information layer on the surface of the spacer layer, and forming a light transmissive layer on the second information layer on the spacer layer. The energy beam irradiating step involves keeping the number of revolutions, starting the irradiation of the energy beam, and thereafter changing stepwise the number of revolutions and the irradiation range.
