摘要

A high-density optical disk (10) contains one or more title sets (84) consisting of files (88) separated by logical sectors, and a volume information file (82) for managing the title sets (84). Each title set (84) includes different files (88) that contain its own management data (141) and reproduction data as an object (144) of reproduction, respectively. To retrieve such an optical disk (10), the volume data file (82) is first read out and management data relating to the procedure for reproducing the reproduction object in the entire volume and the object title set (84) is acquired. Data is reproduced by using this management data (82).
