Abstract: An invention disclosed includes a layer number obtaining section (222) for determining which information storage layer (L1) has been accessed and a layer type identifying section (223) for identifying a type of the information storage layer (L1) determined by the layer number obtaining section (222). With the configuration, even in a case where an information recording and reproducing apparatus accesses an information storage layer different from an intended information storage layer by false operation or the like, it is still possible to dissolve mismatching between a recording or reproduction control scheme being set up and a recording or reproduction control scheme suitable for the information storage layer thus accessed.

Abstract: Disclosed is an information recording medium which, when inserted into a recording/reproducing device, can be run in an updated state intended by a disc supplier since a recordable layer can be specified as a layer to be run first. For example, in an optical disc including an L1 layer which is a read-only recording layer and an L0 layer which is a recordable layer, layer specifying information for specifying the L0 layer in priority to the L1 layer is recorded as an information recording layer to be run first when the optical disc is inserted into the optical disc device which carriers out recording or reproduction of information with respect to the optical disc.

Abstract: In an optical disc (100) having a plurality of recording layers, layer specifying information is recorded for specifying a recording layer to be run first when the optical disc (100) is inserted into an optical disc device (1) which carries out recording or reproduction of information with respect to the optical disc (100). Therefore, a recording layer intended by at least a disc supplier can be run first. In the optical disc (100) including an L1 layer which is a read-only recording layer and an L0 layer which is a recordable layer, layer specifying information for specifying the L0 layer in priority to the L1 layer is recorded as the information recording layer to be run first when the optical disc (100) is inserted into the optical disc device (1) which carries out recording or reproduction of information with respect to the optical disc (100).

Abstract: An optical information recording medium (1) includes, on a substrate (50), a ROM layer (20), a RE layer (40), an intermediate layer (30) separating the ROM layer (20) and the RE layer (40), and a cover layer (10) provided in a position farthest from the substrate (50). The RE layer (40) is an information recording layer provided in a position farthest from the light transmitting layer and also is a recording layer of disc type identification information and an individual identification number recorded in a format allowing easier determination as compared to an information recording format used in the layer allowing only readout of information by use of light irradiation. Therefore, it becomes easy to check a disc type in a recording/reproducing device and one recording/reproducing device can be shared with other types of optical disks. Further, disk production becomes easy.
