A multi-scene program having a plurality of optionally selectable branch stories B0, B1, B2, B3, etc., is recorded between a branch point X and a connection point Y. The preceding main story of a video program, made up of video, sound, text and the like, branches off at branch point X to the branch stories, and at connection point Y connects to the succeeding main story in the video program. The recorded state between the branch point X and the connection point Y is such that the branch stories are each divided into multiple cells and the cells of the respective branch stories are recorded time-division multiplexed. ## Claims ### Claim 1 A recording disc containing a data area for recording data to be decoded, and which stores management data required for reproducing data from
