RECORDING MEDIUM, RECORDER, AND REPRODUCER

摘要

PROBLEM TO BE SOLVED: To provide a new file system for managing more files while maintaining compatibility with conventional file systems. SOLUTION: In a recording medium, subfile management information which consist of the same structure as that of main file management information and subfiles are recorded in a main file system. Moreover, the subfiles and the subfile management information are registered in the main file management information as files. Consequently, such a fault is solved that, when tables treating file management information become insufficient in the case that the capacity of a recording medium is increased, if structure of a file system is changed, the compatibility is lost.
