ABSTRACT:
An optical information recording apparatus, in which an information recording light bream emitted from a laser diode is divided into a plurality of light beams and the light intensities of the divided light beams are modulated by driving liquid-crystal cells formed in a control panel so as to record optical information on a plurality of data tracks and in a plurality of data pits on each of the plurality of data tracks simultaneously. Therefore, according to the present invention, it is possible to make the information recording speed increase without making the apparatus large in size and expensive in cost.
