Camera information recording apparatus for recording image data in an optical disk wherein managing information is stored when the residual storage of a battery decreases

A camera information recording apparatus for recording image data in an optical disk comprising:

• a camera device for producing said image data;
• a data encoding unit for encoding said image data from said camera device;
• digital signal processing unit for processing the encoded data from said data encoding unit;
• an RF amplifier for amplifying the processed data from said digital signal processing unit;
• a laser pickup for recording an output data from said RF amplifier on said optical disk;
• a motor for rotating said optical disk;
• a servo signal processor for controlling the motor;
• a display device for displaying said image data from said camera device;
• and
• a system control unit for controlling said camera information recording apparatus, wherein managing information for managing the output data recorded on said optical disk is produced and recorded on said optical disk when said system control unit detects a decrease in a residual storage of a battery which supplies electricity to said camera information recording apparatus.
