摘要： The present invention makes it possible to strip off a stamper stuck on a resin layer for groove formation during the manufacture of an optical disc from the resin layer without imparting damage or the like to the stamper. The present invention achieves this object by having the steps of bringing about a state in which the stamper protrudes from a substrate by a predetermined width, rotating the substrate with the back surface of the disc-shaped substrate attracted and held, elevating rollers capable of rolling relative to a contacting surface contacting with the protruding portion simultaneously with the rotation, and continuously applying a force working in a direction to separate the protruding portion from the substrate in the circumferential direction of the stamper.

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： The recording data-recording method according to the present invention records recording data encrypted based on a predetermined encryption code on a multilayer optical recording medium comprising two recording layers of a L1 recording layer and a L0 recording layer deposited on at least one side of a substrate. In doing this, the distance between a reference point in the L1 recording layer as a second layer, as counted from an incident direction of a reproduction laser beam or a recording laser beam, and a reference point in the L0 recording layer as a second recording layer, as counted from the incident direction is obtained, and the recording data is encrypted using distance information enabling identification of the obtained distance as the encryption code. This makes it possible to reliably restrict reproduction of recording data from an optical recording medium to which the recording data is copied, while reducing burden on an authorized user.
