An optical disc recording and reproducing apparatus for performing a fomatting process as a background process and a method for formatting an optical disc by a background process

摘要

An optical disc recording and reproducing apparatus can record data, which is provided in a packet having a fixed length, on an optical disc (1) without waiting for a long time for a completion of a formatting operation. The optical disc (1) is formatted by a formatting process as a background process so that another process is acceptable after a start of the formatting process. The formatting process is performed so as to fill at least a predetermined part of a recording area of said optical disc by packets having a fixed length.
