Abstract

1,213,843. Optical recording and playback; audio-visual apparatus. SOC. INDUSTRIELLE DES NOUVELLES TECHNIQUES RADIOELECTRIQUES ET DE L'ECTRONIQUE FRANCAISE. 11 April, 1968 [13 April, 1967; 5 April, 1968], No. 17690/68. Heading G5R. A film F carries a series of images a, b, c, each surrounded by a spiral optical sound track I, II, III. During recording (Figs. 3 to 9) a carriage (P) carrying the film F on a pair of spools (4, 5) is rotated while a light beam from a light modulator (B) is moved radially over the film. During playback (Figs. 10 to 16) the film is stationary and a scanning light beam is moved in a spiral path.
