摘要

On an optical disc (100) having a plurality of recording layers, layer specifying information is recorded that is used for specifying a recording layer to be run first when the optical disc (100) is inserted into an optical disc device (1) for recording or reproducing information on or from itself. Therefore, upon insertion into the optical disc device (1), it is possible at least to initially run the recording layer intended by a disc supplier. On the optical disc (100) including a L1-layer, which is a read-only recording layer, and a L0-layer, which is a recordable layer, layer specifying information is recorded that is used for specifying the L0-layer in priority to the L1-layer as an information recording layer to be run first when the optical disc (100) is inserted into the optical disc device (1) for recording or reproducing information on or from itself. Therefore, upon insertion of the optical disc (100), it is possible to run the optical disc (100) in an updated state intended by a disc supplier.
