ABSTRACT:
A recording apparatus for recording information with a light beam, having a beam deflector for deflecting the light beam in the direction of main scan by a sine wave oscillation. The deflection angle of the light beam from the beam deflector is amplified in the direction of the main scan by means of an afocal anamorphic optical system. This arrangement makes it possible to effect the main scan with the light beam which has been deflected by the light deflector while the angle of oscillation of the light deflector is within a smallest region.
