摘要： A pirated optical recording medium may be determined which is produced by physically transferring a shape of pits and lands formed on a substrate of an optical recording medium. The optical recording medium is provided with excellent weatherability and long-term storage reliability. A reflective film formed of an Ag alloy film of Ag 100-x-y X x Cu y , where X is at least one element among Ti, W, Ta, V, Mo, Nb and Zr, is formed on a substrate on which main data is recorded with a combination of pits and lands. A mark may be formed so that a reproduction signal level in the recorded mark of auxiliary data write once recorded on the reflective film is increased, and a reproduction signal level is decreased in an optical recording medium prepared by physically transferring the surface shape of the pits and lands of the substrate. A pirated optical recording medium may be determined in this manner.

摘要： A pirated edition of an optical recording medium produced by physically transferring the profile of pits and lands formed on the substrate of the optical recording medium can be judged. An optical recording medium excellent in weatherability and having long term preservation reliability is provided. On a substrate recording main data combining pits and lands, a reflection film composed of an Ag alloy film of Ag100-x-yXxCuy, where X is at least one kind of element among Ti, W, Ta, V, Mo, Nb, Zr, is formed so that a mark for elevating the record mark reproduction signal level of write once recording sub-data to the reflection film but for lowering the reproduction signal level in an optical recording medium produced by physically transferring the surface profiles of pits and lands on the substrate can be formed, thus judging a pirated edition of optical recording medium.
