Abstract
A laser recording method including: deflecting a plurality of laser beams, respectively and dividing the respective beams into multiple beams which are at substantially regular intervals; linearly arranging respective beams of the multiple beams in a line at substantially regular intervals and in a direction perpendicular to a direction of scanning action of the beams on the recording medium; modulating each beam and focusing the beam on the recording medium; and scanning the recording medium with the divided beams.
Claims17
An optical recording method for recording image information upon a recording medium, comprising the steps of:
- forming at least two light beams;
- projecting said light beams along first and second paths, respectively;
- dividing and simultaneously modulating each of said light beams to form respective first and second groups of modulated beams, wherein the beams of each said group are spaced along respective first and second imaginary straight lines, each of which projects through the beams of its associated group and is disposed substantially perpendicular to the directions of travel of the beams;
- directing each said group of beams through optical means for disposing such groups in a common array wherein the linearly spaced beams of each group are linearly spaced from the beams of the other group along a third substantially straight line projecting through each of said modulated beams and substantially perpendicular to their directions of travel;
- and
- scanning said recording medium with said array of modulated beams to form straight lines of image information on said recording medium in a direction substantially perpendicular to the scanning direction.
