ABSTRACT:
A recording medium scanning system includes a light source for generating a scanning light beam, a light modulator for modulating the light beam with a modulating signal, and a scanner for scanning a recording medium with the modulated light beam emitted from the light modulator. The scanning speed of a light beam emitted from the scanning means is detected by a scanning speed detector which issues a scanning speed signal indicative of the detected scanning speed. An arithmetic operation such as a multiplication or a division is effected on the scanning speed signal issued from the scanning speed detector and a recording signal. The result of the arithmetic operation is applied as the modulating signal to the light modulator.
