Abstract: More efficient methods are being used for sound transfer in the production of 8mm magnetic prints. From single 8mm recording using commercial magnetic projectors at sound speed, the operation has changed to the use of several single 8mm recorders running together. Equipment was developed for the simultaneous transfer of four tracks on 35mm striped color print film, perforated 5R-1500. When the four prints are exposed on a reduction printer with the four apertures staggered, the problem of designing a professional recorder becomes more complex. The design was intended not only to solve the problem of recording four staggered-sync soundtracks simultaneously, but to eliminate equipment, production and quality problems of the earlier systems. A rerecording system which overcomes these problems is described. In addition to the decreased film handling and increased production output, the system provides improved sound quality.
