Tape transport control system

摘要: A tape transport control system for monitoring the amount of on a reel using first transducer means to provide signal representative rotational speed and second similar representation drive capstan. The signals from transducers are compared by comparator circuit determine remaining which condition is represented predetermined ratio output obtained capstan means. can be used reverse or stop prevent completely unwinding monitored reel. In reel-to-reel system, sensing automatically switched one other upon detection low in previously reel, operation reversed full empty
