ABSTRACT:
A recording head includes electrothermal transducers associated with temperature sensing elements. A method for driving the recording head includes supplying driving energy to the electrothermal transducer, and evaluating a temperature change in a temperature fall interval, occurring after supplying of driving energy to the electrothermal transducer, based on temperature information acquired from the temperature sensing element. The method further includes changing a setting value of the driving energy supplied to the electrothermal transducer, determining an energy value for driving the electrothermal transducer based on the evaluated temperature change and an energy value supplied to the electrothermal conversion element, and recording data on a recording medium by driving the electrothermal transducer according to the determined energy value.
