PROBLEM TO BE SOLVED: To enable a user to record and reproduce audio data with a system easily usable by the user, including both of a continuous recording system and a file system, with good operability. SOLUTION: The audio data is recorded by the continuous recording system on the inner peripheral side of a disk and the audio data of the file system is recorded on the outer peripheral side. The recording region of the audio data of the file system on the outer peripheral side is made higher in density than the density in the recording area on the inner peripheral side.
