ABSTRACT:
In order to effect recording on a recording medium by projecting a beam on the recording medium, the beam must be deflected at a predetermined velocity. To deflect the beam at a predetermined velocity, the present invention detects the deflected beams by a beam detector to form a velocity signal and compares the velocity signal with a reference signal to control the motor of the deflector by the comparison output.
