Abstract
A light beam projecting system comprising a light source and a condenser lens system is mounted on a rotator to project radially outwardly a light beam modulated by a desired modulating signal representing information to be recorded while rotating together with the rotator. The rotator is mounted for movement in the direction parallel to the rotational axis thereof whereby the light beam emitted from the light beam projecting system is caused to scan a recording medium opposed to the peripheral surface of the rotator to record the information thereon.
