ABSTRACT:
A thermal recording device records information on a heat-sensitive recording material which develops color in a density according to heat energy supplied thereto. The thermal recording device pre-heats the heat-sensitive recording material with heat energy less than energy necessary to develop color in the heat-sensitive recording material and scans the recording material with a laser beam modulated according to the information to be recorded. A region from the upper surface of the heat-sensitive recording material to a space above the upper surface of the heat-sensitive recording material through which the laser beam impinges upon the heat-sensitive recording material is isolated from the surrounding space at least at its sides and top by side isolating members and a top isolating member, and at least the top isolating member is transparent so that the laser beam impinges upon the heat-sensitive recording material through the top isolating member.
