The navigation generator 12 sets the time length of a VOB to a time length that is determined in advance depending on a scheduled recording time H. Even if a user makes an operation to stop the recording before the time length of a recorded part of the VOB equals the predetermined time length, the VOB of the predetermined time length is recorded onto a DVD±R. Cell information specifying the part of the VOB preceding the point corresponding to the recording stop is generated. Then, PGC information containing the Cell information is recorded onto the DVD±R.
