Abstract: There is provided an optical information recording medium including a plurality of laminated resin layers, and an inorganic layer that is formed in an interface between the resin layers. Storage elastic moduli are different when the interface is assumed to be a boundary. An information signal is recorded in the interface.

Abstract: An information signal area on an information signal recording surface is provided as pits on a mirror in accordance with modulated information data, and is covered with a metal alloy reflective film. Sections that do not include pits corresponding to the information data are provided in the information signal area, and portions of the metal alloy reflective film on the sections are formed as perforated marks corresponding to the information data. In this case, the reproduction signal amplification level of a prepit signal and the reproduction signal amplitude level of a perforated mark signal can be obtained as substantially equal values by adjusting the depth and width of pits and/or adjusting the width and length of perforated marks. Hence, waveform distortion due to a waveform equalization circuit and variations in binary signals due to displacement of the slice level are reduced so that signals can be stably and reliably detected with the same reading apparatus.

Abstract: [Object] To enable stable void recording to be performed with lower power than in a case where a conventional void recording method that records hole marks (voids) in a bulk layer is adopted. [Solving Means] First laser light is irradiated onto an optical recording medium in which a plurality of resin layers are formed while the first laser light is focused on a boundary surface of the resin layers, to thus record hole marks onto the boundary surface. Since a recording sensitivity of the hole marks is enhanced at the boundary surface of the resin layers, by recording hole marks onto the boundary surface as described above, laser power requisite for recording can be suppressed as compared to the conventional art. As a result, it becomes unnecessary to use a special laser such as a short-pulse laser, and even if a CW laser (CW: Continuous Wave) is used, a recording speed does not need to be sacrificed.

Abstract: [Object] To enable stable void recording to be performed with lower power than in a case where a conventional void (hole) recording method is adopted. [Solving Means] Provided is an optical recording medium including a recording layer in which a plurality of boundary surfaces of resin layers are formed, and intervals of the boundary surfaces are set to be equal to or smaller than a focal depth of recording light. A recording sensitivity of hole marks is enhanced at the boundary surfaces of the resin layers. Therefore, by providing the recording layer in which the boundary surfaces are provided at intervals equal to or smaller than the focal depth of recording light as described above, that is, the recording layer is practically filled with the boundary surfaces, the hole mark recording sensitivity of the recording layer can be enhanced as a whole.

Abstract: 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 Ag100-x-yXxCuy, 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.
