  • Thermal head, producing method therefor, and recording apparatus using the thermal head
    Patent number: 5097272
    Abstract: A thermal head serves as a recording head used in a thermal recording apparatus for performing a recording with heat produced by an electric current flowing into a thick-film resistor. Regions having higher resistance than that of the thick-film resistor are disposed in the thick-film resistor and heating portions each corresponding to one dot in the thick-film resistor are controlled by electric current flowing therethrough from one of first electrodes to one of second electrodes provided in the thick-film resistor. A heating control method for such thermal head attains superfine recording and halftone recording and a method produces such a head and a recording apparatus using the head.
