Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a method for controlling a laser diode which can quickly start a wire operation even when the laser diode is at a temperature lower than an operation guaranteed temperature when it is cold. SOLUTION: An apparatus for controlling the laser diode is provided with a temperature sensor for detecting the temperature of the laser diode. When the temperature of the temperature sensor is lower than the predetermined value of the laser diode, a current corresponding to the threshold current of the laser diode is supplied to the laser diode. After the lapse of a predetermined period, laser beams are outputted to raise the temperature of the laser diode to the operation guaranteed temperature and thereafter, the writing operation is started.
