Abstract:
An information recording apparatus for recording independent additional information after recording independent principal information on an information recording surface of a heat-sensitive recording medium that develops at least one color in response to thermal energy applied thereto, comprising:application means for applying said thermal energy and pressure to a protection layer of said information recording surface of said heat-sensitive recording medium for recording said independent additional information after said independent principal information is recorded; and control means for controlling said thermal energy applied by said application means, wherein said control means controls said thermal energy applied by said application means based on energy-gloss characteristics of said heat-sensitive recording medium for recording said independent additional information on said protection layer of said information recording surface of said heat-sensitive recording medium using variations of glossiness based on said energy-gloss characteristics of said heat-sensitive recording medium after said independent principal information is recorded.
