FIELD: physics.
SUBSTANCE: proposed device comprises laser, beam splitter to divide laser beam into two parts, one intended for imaging object beam and comprises data input matrix device Fourier-conversion lens, the other part serves to form reference beam shaped as required in perpendicular incidence of the latter on surface of recording medium, recording medium turn drive with turn axis aligned with reference beam axis. Spatial light modular is introduced in reference beam to make selective writing and recovery of data pages recovery by reference beam phase coding.
EFFECT: higher density of data writing.
