  • Patent number: 3969663
    Abstract: A control system for precisely locating a tape upon deceleration thereof from a transport velocity to rest. A signal is generated which represents the distance traversed by the tape subsequent to an identified event. The signal is compared with a reference signal representing a desired distance-versus-time characteristic, and the error signal thus given rise to is used to either "plug" or dynamic brake the motor to control the stopping distance. Final position control logic produces and additional enabling signal should the tape overrun its desired position, and causes the motor to reverse to reposition the tape. In a preferred embodiment, a current limit circuit monitors current through the drive motor, and intermittently disables a portion of the drive circuit in response to a sensed overcurrent condition.
