Abstract

721,551. Optical sound recording. CINEMATELEVISION, Ltd. Feb. 17, 1953 [Feb. 21, 1952], No. 4615/52. Class 40 (2). In a method and apparatus for recording a variable area track on photographic film 9, the light source comprises an elongated image 6 on a cathode ray tube 4, the said image being deflected in the direction of its major dimension by the signals to be recorded. A mask 7 is arranged between the cathode ray tube 4 and the film 9 in such a position that in the absence of a signal the image 6 is completely obscured. During maximum intensity of the signal being recorded, the image vibrations extend to the position 6a.
