A Versatile Multiple-Unit Re-recorder
Glen R. Crane, H. A. Manley · Journal of the SMPTE · 1959
The Re-recorder is a machine designed for small studio use and incorporates in one cabinet up to four magnetic reproduce units driven by a common motor. The units may be any combination for either 35, 17 1/2, 16mm or 1/4-in. perforated film, one of which may be equipped for magnetic recording and a second for optical reproduction. Transistorized amplifiers of new design have been incorporated.
