Abstract
Additional recording data is written continuously with data already recorded on a disk and writing of additional data is started in synch with recorded data. The optical head reads data recorded on the disk just before recording is halted every time the record decision unit judges that recording is to be halted. The record-status detection unit detects the formation status of the recorded data. The head output control unit sets the luminous output of the optical head 1 at the beginning of additional writing according to the recording state judged by the record-state detection unit . Thus, the formation status of data recorded on a disk is detected to allow the luminous output of the optical head to be set to an optimum record level.
