PURPOSE:To enable to obtain high thermal efficiency and to prevent wear of a recording head, by providing a recording medium, of two-layer structure, made of thermal insulating material and/or low friction material in the recording head side thereof. CONSTITUTION:A film 1 consists of a metal film layer 1A, having a thickness of 8-50mum, made of nickel or stainless steel or the like and a thermal insulating material 1B applied with a thickness of coating or adhesion of 2-20mum with resin having high thermal resistance and lubricating ability such as fluororesin, e.g. ethylenetrifluoride, and polyamide resin and the like, or ceramics such as SiO2. When the expansion of the bubble in an ink 5A caused by heat-up of a head 7, results in flowout of an ink 5B on a sheet 9, the thermal insulating material layer 1B helps the heat of the thermal head 7 transmitted from a heating element 6 to have the minimum flowout to the film 1 so as to save excess electric power. In addition high lubricating ability enables the expensive thermal head to be less weared and to obtain longer service life. |
