  • Method and apparatus for controlling the movement of a recording medium
    Patent number: 4224645
    Abstract: A recording medium transport control precisely controls the movement of a recording medium such as magnetic tape at a desired velocity. A pulse drive control adapted for manipulation provides drive pulses to the transport. Each drive pulse is of a variable duration sufficient to drive the transport so that the medium is moved a predetermined distance. One embodiment of the present invention includes a velocity servo drive control, also adapted for manipulation, for providing an adjustable continuous drive signal to the transport and a switch for switching control of the transport from the pulse drive control to the velocity servo drive control when the velocity of the transport reaches a predetermined cross-over velocity.
