ABSTRACT:
A table of a management region on the disc contains a disc identifier that represents the type of the data recording format of the disc, a number-of-disc-sides identifier that represents whether the disc is a single-sided disc or a double-sided disc, and a disc side identifier that represents whether the reproducing disc is side A or side B of a double-sided disc. A disc identifier 4 that represents the type of the data recording format of the file is recorded in a file (n) table including management information of the file. A reproducing apparatus reads the disc identifiers from the PVD table and the file (n) table and determines whether or not the disc and the file are reproducible. In addition, the reproducing apparatus reads the number-of-disc-sides identifier 2 from the PVD table and determines whether or not the disc is a double-sided disc or a single-sided disc. When the disc is a double-sided disc, the reproducing apparatus determines whether the reproducing side is side A or side B.
