ABSTRACT:
Information is recorded on a heat-sensitive recording material including a photo-thermo conversion agent which converts supplied light energy into heat energy, a developing agent and a color forming agent which is encapsuled in micro-capsules whose permeability to materials increases with increase in said heat energy and forms a color by reaction with the developing agent. The photo-thermo conversion agent is localized in and/or on the micro-capsules. The heat-sensitive recording material is heated by supplying the heat-sensitive recording material with heat energy less than energy necessary to cause the heat-sensitive recording material to form a color. A light beam modulated according to the information to be recorded is caused to scan the recording material.
