摘要

Support u00e0ptico combined device to access a support u00e0ptico, apparatus comprising the device, method of accessing a support u00e0ptico combined, and support legu00cdvel by computer. A combined optical disk (1) is exposed, which contains at least two layers of information (10, 11) of at least two different storage formats selected from, for example, CD, DVD, BD.The data are stored on the disk in relation to the storage format of the layers (10, 11). According to one mode of the invention, each of the formats contains information indicating that a second or even a third format is present on the same disc. After a device may select a format different from that detected during the game.Alternatively, all formats on a single disc are identified by an identifier on the disk.
