ABSTRACT:
A circuit for uniformly controlling the velocity of a sled of a disk drive includes a circuit for converting a velocity to a frequency through a speed sensor used for driving the disk drive, a circuit for amplifying a voltage of the speed sensor to a stable value, a circuit for converting the frequency to a voltage variation value, a circuit for selecting and maintaining a maximum value of the voltage variation value, a circuit for forwardly/backwardly inverting the voltage variation value, and a circuit for carrying out subtraction between the inverted value and a shift control signal, with the result of the subtraction being applied to a drive circuit to minimize power consumption.
