Abstract
An information recording apparatus and an information recording method are provided for recording additional information on a heat-sensitive recording medium with a simple configuration without seriously affecting a main recorded image. A CPU includes a memory for storing the additional information. The CPU further includes a memory for storing information about thermal energy and glossiness of the heat-sensitive medium. Based on the information about gloss characteristics, the CPU controls a thermal head through a head controller so that a specific amount of thermal energy is applied to an image recording surface of the medium after image recording. The thermal energy applied effects variations of glossiness corresponding to the additional information to record. Through the application of the thermal energy, glossiness of the medium varies and the additional information is thereby recorded on the medium.
