Abstract
Abstract Methods and apparatus for recording a plurality of dissimilar signals such as the brightness, color and sound signals forming part of television signals, said signals being simultaneously generated by a generating means, said signals then being respectively memorized by individual memories and read out in accordance with a predetermined order, said read out signals being applied to the control electrode of an electron beam recorder in order to modulate the beam intensity, said signals then being finally recorded in monochrome on a radiant energy sensitive recording medium, and recorded at different positions on the recording medium in transverse formation.

Claim 1
Independent Claim
202 words
A method of recording sets of signals, each comprising a plurality of dissimilar simultaneously generated signals at different positions on an elongated radiant energy sensitive recording medium in transverse formation comprising the steps for: A. longitudinally conveying said recording medium; B. periodically scanning a radiant energy beam in the transverse direction of said recording medium; C. storing a first set of signals comprising a plurality of dissimilar signals in a first set of different memories, the number of said memories corresponding to the number of said dissimilar signals included in one line scan of said radiant energy beam; D. sequentially reading out of said first set of different memories said stored signals to control the intensity of said radiant energy beam during one scan; E. storing the following set of signals comprising a plurality of dissimilar signals in a second set of different memories, the number of said memories corresponding to the number of said dissimilar signals, said signals being generated during the reading out time of the stored signals in said first set of memories (step D); F. alternately storing and reading out of said first and second sets of memories to control the intensity of said beam during succeeding scans.
