ABSTRACT:
A video tape duplicator for duplicating a video signal simultaneously on a plurality of video tapes at high speed. The duplicator includes a source for providing a high frequency video signal and a record head for simultaneously recording the high frequency video signal on a plurality of duplicate magnetic tapes. The record head rotates at a speed which is related to the frequency of the high frequency signal so that the duplicate tape may be played back at normal head and tape speeds.
