Multi-beam zoom and focusing lens scan pitch-adjusting recorder

摘要

A method for recording a plurality of reproduction picture images of an original picture in which multiple laser beams modulated by an acoustic-optical modulator according to picture signals obtained by scanning the original picture in a scanning image reproduction system and an apparatus for carrying out the above described method. Particularly in the invention there is disclosed a means for adjusting mutual distance between each of the plurality of parallel laser beams in response to desired scanning line pitches.
