For example, the DVD system of the various types like the playback private DVD-Video system and the postscript type DVD-VR system exists. The disk of the DVD-VR type which houses the bitstream of DVD-VR type should play back with the recorder or the player of DVD-VR type. But, also it is possible to record the bitstream of DVD-Video type to the disk of DVD-VR type with the recorder of DVD-VR type, to play back that disk with the player of DVD-Video type. The bitstream of special type is assembled, is recorded to the reproducible disk with the player of both type. As for the bitstream of this special type, is a DVD-Video system and a DVD-VR system and compatibility. Vis-a-vis the both system, the addition file which corresponds is added to those private directories, but the bitstream which can vis-a-vis both system type expresses the completely same file on the disk. The DVD-VR player and the DVD-Video player being both, to play back it is possible the medium which houses the bitstream which possesses this kind of data structure.
