Substrat für thermischen Aufzeichnungskopf und thermischer Aufzeichnungskopf unter Verwendung dieses Substrats.

摘要

The present invention concerns a thermal recording to be used for performing recording, preferably an ink jet thermal recording, a process for forming the same and a recording apparatus by use thereof, and accomplishes uniformized heat energy action of the heat acting surface (protective layer surface when there is protective layer) played primarily by the heat-generating resistors (102) of a plurality of electrothermal transducers (111). The present invention, for that purpose has uniformized the amount of heat energy generated during recording at the plurality of heat acting portions by positively changing the shape or the thickness of the resistors (102) concerned with the heat acing portions or/and the constitution itself of the protective layer depending on its existing position.
