ABSTRACT:
To provide a method for optimizing the optical output from an optical head when recording data onto an optical disk, each time a suspension of data recording onto the disk is determined, the optical head reads data recorded onto the disk before the suspension, and recording state of this data is judged. Based on the judged recording state, the optical output from the optical head to be emitted when resuming the data recording is controlled. A timing at which to suspend data recording can be desirably set, so that the recording state of the recorded data in the disk can be judged at desirable timing in data recording operation, so that the optical output from the optical head is controlled based on the judged recording state.
