PROBLEM TO BE SOLVED: To provide a method of processing a buffer underrun when files are being recorded in an optical disk. SOLUTION: When files are being recorded, tracks for recording file system for recording files in an optical disk are reserved, and then the files are recorded to tracks that logically succeed to the reserved tracks. When a buffer overrun occurs, the current track is closed and a gap is inserted so as to allow recording to the succeeding tracks. After the file is recorded, a path table and a directory descriptor are recorded, and then volume descriptors are recorded, and then volume descriptor of the file system is recorded to the reserved tracks.
