PROBLEM TO BE SOLVED: To make file management easy even if the number of files largely increases to manage including video files. SOLUTION: In the allocation descriptor, the position information of the extent is designated by the logical block numbers. The length of the logical sectors are the same 2,048 bytes as the physical sectors, and the logical blocks and the logical sector have the same length. In the video file, AV addresses are set up in the unit of a logical block of 2,048 bytes basically in the same order as the descriptions in the allocation descriptor in the file entry.
