Abstract
Abstract In a super density optical disk (10) for storing video data, video data is compressed to packs (88, 89, 90, 91) defined in MPEG and trains of the packs (88, 89, 90, 91) are stored in an video object unit (85). The video object unit (85) includes a navigation pack (86) which is placed at the head of the pack train. In data cell (84), a plurality of video object units (85) each being reproduced within a predetermined period are arranged and a cell playback information table (107) describes a cell playback information which defines a playback order of the cells (84). The navigation pack (86) has an area storing playback information for reproducing each video object unit (85) and search information for indicating the relationship with other video object units (85). The data cells (84) and the cell playback information table (107) are stored in the optical disk (10).
