Abstract
In a laser beam scanning system for recording information of characters and/or marks on a heat mode recording material, the pulses used for modulating the laser beam according to the information to be recorded are extended by 10% to 100%. By the extension, the dots or the minimum elements recorded on the recording material are expanded in the main scanning direction. Thus, the thickness of the lines constituting the character or the like are recorded in the constant thickness both in the vertical and horizontal directions. The pulses are delayed and the delayed pulses are added to the original pulses to obtain a logical sum thereof, thereby obtaining extended pulses. Alternatively, the fall of the pulses is detected and other pulses are generated upon detection of the fall, and the original pulses and the other generated pulses are added together to obtain extended pulses.
