Abstract
A recording apparatus including a beam generator for generating a beam modulated by a modulating signal supplied thereto; a deflector for deflecting the beam generated by the beam generator repeatedly in two directions; a recording member for receiving the beam deflected by the deflector and recording the trajectory of irradiation by the beam; a recording information storage for storing information to be recorded on the recording member; the recording information read from the information storage being supplied to the beam generator as the modulating signal; a beam detector provided in the deflecting area of the beam deflected by the deflector and adapted to release a beam detection signal upon detection of arrival of the deflected beam at the detector; and a signal forming device adapted for selecting either one of two consecutive beam detection signals released from the beam detector thereby forming a reference signal for instructing the initiation of the readout from the recording information storage.
