Editing Tape recorder (section)

=== Photoelectric paper tape recorder ===
In 1932, after six years of developmental work, including a patent application in 1931,<ref>USPTO. [https://books.google.com/books?id=gCegAAAAMAAJ Official Gazette Of The United States Patent Office], United States Patent Office, 1936, Volume 463, pp.537.</ref><ref>USPTO. [https://patents.google.com/patent/US2030973 United States Patent Office, Patent US2030973 A, "Method of and apparatus for electrically recording and reproducing sound or other vibrations"]</ref> Merle Duston, a [[Detroit]] radio engineer, created a tape recorder capable of recording both sounds and voice that used a low-cost chemically treated paper tape.  During the recording process, the tape moved through a pair of electrodes which immediately imprinted the modulated sound signals as visible black stripes into the paper tape's surface.  The [[audio signal]] could be immediately replayed from the same recorder unit, which also contained photoelectric sensors, somewhat similar to the various [[sound-on-film]] technologies of the era.<ref>Popular Science.
