ABSTRACT:
An image recording apparatus and method use an acoustooptic element as a shutter element and as a device to scan two different beams. The beams are diffracted by modulating the acoustooptic frequency of the acoustooptic element to form band-shaped spot rows on a moving image recording medium. The spot rows include a first beam row and a second beam row that are incident on the image recording medium at different times. The positions of the adjacent beam spots of the first beam row are adjusted relative to the positions of the adjacent beam spots of the second beam row.
