Abstract
According to the improved method of thermal recording with a thermal head, each time a specified amount of thermal recording has been performed, a coating layer is formed in a specified area of the surface of the protective layer on the glaze of the thermal head and, thereafter, the thermal recording operation is resumed. The improved thermal recording method and the improved thermal recording apparatus to which this method is applied permit a coating layer to be present at all times on the surface of the protective layer on the glaze of a thermal head; hence, a great number of prints can be produced without causing the wear and corrosion of the protective layer, thereby assuring that the thermal head is long-lived to maintain high operational reliability over a prolonged period.
