摘要： An optical disc having a protection layer for protecting a recording layer located farther from a substrate and having a first recording layer and a second recording layer stacked on one side of the substrate, wherein the reflectance of one of the first and second recording layers is made higher than the reflectance of the other recording layer, and a reproducing device which uses this optical disc. The reproducing device casts a light beam emitted from a single light source onto the first recording layer or the second recording layer via a single objective lens, discriminates which of the first recording layer and the second recording layer the light beam emitted from the light source is cast on, on the basis of the result of detection of a reflected beam from the first recording layer or the second recording layer, moves the objective lens in a direction parallel to the optical axis of the objective lens on the basis of the result of discrimination, and condenses the light beam on the first recording layer or the second recording layer so as to carry out reproduction of information.

摘要： An administrative system receives unique ID information of disk from an orderer for ordering manufacture of the disks and provides the unique ID information for a disk maker. The maker stores on the disk unique attribute information of the disk including identification information for the disk maker side. The administrative system obtains normal recording information generated if normal recording is carried out when recording on the disk the unique attribute information of the disk. Alternatively, the administrative system obtains abnormal recording information generated if abnormal recording is carried out. Disk administrative information, for example, number of pieces of the disks delivered from the factory, is generated from the obtained normal and abnormal recording information.

摘要： A method for reproducing a recording medium comprising reading out identification data from a recording medium having recorded thereon data and the identification data, which identification data includes entity identification data and detection data. The detection data is generated using at least the entity identification data and indicates whether or not the entity identification data at least is authentic data. The identification recorded on the recording medium is read out, detection data is generated based on the entity identification data of the identification data as read out and the detection data extracted from the read-out identification data is compared to the generated detection data. When, as a result of comparison, the detection data extracted from the read-out identification data is coincident with the generated detection data, the outputting of the data read out from the recording medium is permitted.
