ABSTRACT:
AV stream files and original management files are initially recorded in a first data recordable area of an optical disc. After the recordation of the original management files in the first data recordable area, at least one backup management file is recorded in a second recordable area of the disc. When associated original file system information is recorded in the first data recordable area after the recordation of the backup management file, backup file system information is recorded in a third data recordable area. All of the first, second, and third data recordable areas are closed after the recordation of the backup file system information.
