PHONOGRAPH RECORD IS MADE ON PAPER (Feb, 1932)

PHONOGRAPH RECORD IS MADE ON PAPER

Phonograph records on paper, costing a cent or two apiece and playing twice as long as standard records, are promised by an entirely new process developed by two young Argentinian engineers. In principle the scheme resembles the method used for sound motion pictures. Apparatus in the recording studio transforms a singer’s voice into a flickering beam of light, leaving a sound track of black and white lines upon a sheet of photographic paper moving beneath it upon a revolving drum. The reproducer employs a photo-electric cell to translate the lines back into sound. The paper record is shown above.
