Optical disk apparatus

An optical disk apparatus comprising:

• a recording unit for recording data on an optical disk set on an apparatus main body;
• a temporary data recording unit for temporarily recording target data to be recorded on the optical disk on a non volatile recording medium when the recording unit records the data on the optical disk, and for deleting the target data from the non volatile recording medium after the recording unit completes recording of the target data on the optical disk;
• and
• a repair unit for commanding the recording unit to record data which remains on the temporary data recording unit without being deleted therefrom when the power source of the apparatus main body is turned on and the optical disk is set on the main body, wherein:
• the temporary data recording unit records identification information for identifying an optical disk where data is recorded while associating this data with the optical disk where this data is recorded;
• the repair unit commands the recording unit to record data which is associated with the identification information corresponding to the optical disk set on the apparatus main body and remains on the temporary data recording unit without being deleted therefrom when the power source of the apparatus main body is turned on;
• and
• the recording unit transfers the target data to the temporary data recording unit so that the temporary data recording unit can record the data on the non volatile recording medium immediately before recording of the data on the optical disk starts.
