Modifications of Tape Reproducing Equipment for Use with the Pilot-Tone Synchronization System

Rudolph R. Epstein, Leo H. O'Donnell

Motion-picture production requirements for lightweight synchronous location equipment demand battery-operated cameras and magnetic recorders. The speed variations of the location equipment are recorded on a low-frequency control track at the center of the 1/4-in. tape perpendicular to the program modulations. The recordings are reproduced and speed corrected with a playback synchronizer originally designed for a high-frequency carrier system of synchronous recording. The modifications of the synchronizer for this additional use are described and performance data given.
