An apparatus, system, and method are disclosed for the velocity
proportional clocking of time base servo tape storage devices. The
apparatus, system, and method allow the velocity of time base servo tape
storage devices to be adjusted and maintained by adjusting the frequency
of a clock. In one embodiment, a velocity command is received and the
clock signal frequency is varied in response to the command. A feedback
control signal may then be produced to control the velocity of a time
base servo device in response to the clock signal frequency, the feedback
control signal being used to vary the velocity of a servo motor. In one
embodiment, the velocity of the servo motor varies directly proportionate
to the clock signal frequency.
