Abstract
An optical recording apparatus includes a light-transmitting diffraction grating at a front focus of an imaging lens and a multi-channel acousto-optic modulator provided at a back focus of the lens. An angle formed between a plane formed by diffracted beams emerging from the lens and a revolution surface of a rotating polygonal mirror is set to be equal to an angle at which the beam diffracted by the multi-channel acousto-optic modulator emerges to be incident on the mirror. The diffracted beams are incident on the imaging lens to satisfy a predetermined condition.
