Abstract
In a disc drive, a voice coil motor is configured to drive an actuator with mainly torque, thereby reducing unwanted vibration of the actuator. The voice coil motor includes a moving coil vertically disposed with respect to a horizontal radial magnetic field provided by a stationary unipolar magnet such that the active portions of the coil are of different radial separation from the actuator pivot. A yoke facilitates closure of the magnetic flux paths.
