An optical high density recording device which comprises, in combination, a beam generator, a beam modulator to modulate the beam in accordance with an applied modulating signal, a recording medium to record a locus of the beam irradiated thereonto. The recording medium and the beam irradiated onto the recording medium are moved relatively to one another, a recording signal is introduced onto the recording medium, a corrective voltage to be determined by a function of the recording signal is generated and is applied with the recording signal to the beam modulator as a modulating signal.
