Abstract
A disc drive has rotatable recording disc and a transducing head on a slider arranged to fly over a surface of the disc when the disc is rotated. The slider is supported by an actuator arm operatively coupled to an actuator motor to position the transducing head over a selected track of the disc. The slider is arranged to land on the disc surface when the disc is not rotated. Dithering means vibrates the slider when the slider is on the disc surface to reduce stiction between the slider and the disc surface thereby reducing the torque required to commence flying of the slider.
