Abstract
The improved thermal recording system uses both a thermal head having a layer to protect heaters and a thermal recording material in which a thermal recording layer unit has a water content of no more than 6 wt. %, the protective layer of the thermal head comprising at least one ceramic-based lower sub-layer which is overlaid with a carbon-based upper sub-layer. This thermal recording system improves the wear resistance and electrical insulation of the protective layer on the thermal head so markedly that high operational reliability is insured for an extended period of time.
