摘要
A method and apparatus are applicable to a thermal recording system which records data in a recording medium using a heat generated by applying a power to a resistor. According to the invention the resistor itself or a monitor, which is disposed in the path of electric current applied to the resistor, is made of a material having the metallic/non- metallic phase transition characteristics at predetermined temperature, whereby the resistor or the monitor can have a function to interrupt the electric current at the predetermined temperature so that the peak temperature of the resistor s controlled constantly regardless of the value or period of the applied voltage. Further, it achieves a uniform recording property and a stable continuous tone recording property by controlling the period for holding the peak temperature of the resistor.
