PROBLEM TO BE SOLVED: To provide an optical disk in which three-dimensional videos and high-quality video images are recorded and a system for reproducing them, which achieves compatibility with the conventional system for reproducing ordinary videos. SOLUTION: Interleave blocks are obtained by dividing first and second video signals into frame groups of one GOP or more and alternately recording the video signals on the right and left sides on an optical disk 1. In a three-dimensional/high-quality image compatible reproducing device, either stereoscopic videos or high-quality videos are obtained by reproducing both of the first and second interleave blocks. In a three-dimensional/high-quality image non-compatible reproducing device, ordinary videos are obtained by reproducing only one of the first and second interleave blocks by performing track jump.
