ABSTRACT:
A track jump control circuit includes a head; a rotary motor which drives the head and is controlled in accordance with an input signal; a unit for detecting a speed of rotation corresponding to the rotation of the rotary motor; distance detection unit for producing a signal corresponding to a distance which the head should move with using no data read by the head when the head is moved to a desired position; speed setting unit for setting a speed of movement of the head based on the signal produced by the distance detection unit; and a unit for comparing a speed detected by the speed detection unit with a speed set by the speed setting unit to produce an output as the input signal to the rotary motor.
