Abstract
A heat-sensitive recording head having heat generating elements arranged on an insulating substrate and a system for preheating said substrate and controlling the heat generated during the recording operation. In one embodiment the substrate is placed in contact with a larger heat sink which is heated by a carbon-type internal resistor, a printed circuit contacting resistor, or a conventional heater. A thermal sensor detects the temperature of the heat sink and is fed to controls for controlling the overall application of heat. In another embodiment the substrate is placed in contact with a Peltier effect device which controls heat generation and absorption.
