Abstract
Abstract Recorded at high density on an optical disk (10) are at least one title set (84, 86) and a volume information file (82). The title set consists (84, 86) of a plurality of files (88) aligned on a boundary between logical sectors. The files (88) store title set management information and data objects to be reproduced. The retrieve data from the optical disk (10), volume file information is read out, thereby acquiring information about the desired title set (84, 86). Then, the information for indicating steps or reproducing the data object and managing the desired title set (84, 86) is acquired. Using the title set management information, data is reproduced from the optical disk (10).
