Abstract
Abstract An overlay recording device for recording first information and second information in a superimposed mode on a recording medium by reading out the first information from storage in a first memory and the second information from storage in a second memory, thereafter converting the respective first and second information so read out into first and second dot signals, modulating a beam with logic outputs of the first and second dot signals to thereby form a beam modulated by the first information and the second information, and scanning the recording medium with the modulated beam.
