ABSTRACT:
A control system for operating two magnetic tape loop bins in series with a continuous tape having an end of tape marker, including guides and drive rollers or capstans for guiding a tape from the first bin to the second bin and from the second bin past a magnetic head station to the first bin. End of tape sensors are positioned between the first and second bins and between the second and first bins to provide signals when tape markers pass the respective sensors. Each bin is provided with a tape drive motor and a motor control, with one motor being driven to provide about a constant tape tension and with the other motor being driven at a controlled speed which varies as a function of an error signal determined from the tape marker sensors.
