A method and a circuit for controlling a slew rate of a coil in a voice coil motor in a disk drive system. A slew rate control signal is generated by a microprocessor or by an analog circuit in response to one or more operating parameters of the disk drive system. A driver circuit selectively couples the coil between a voltage source and a ground in response to a driver signal, and controls the slew rate of the coil in response to the slew rate control signal.
