ABSTRACT:
A dot character recording device in which a recording surface is scanned with a laser beam modulated in accordance with the dot patterns of characters to be recorded. The time width of the modulating signal is adjusted in accordance with the beam position in order to maintain a constant scanning line and hence character dot width. Preferably, the pulse width of the modulating signal is increased in the scanning direction at recording positions where the density of the beam would otherwise be low so as to apply additional optical energy.
