Abstract
A servo system for controlling the movement of one or more magnetic transducer heads relative to rotating magnetic disc surfaces which are supported and transported by means of a linear actuator motor having position and velocity modes of control, and which additionally has an anticipatory mode of control which provides a compensatory signal proportional to the rate of change of the servo velocity error over the operating frequencies of the system so that the linear actuator motor is responsive to both the velocity error and compensatory mode signals to reduce velocity overshoots from a predetermined programmed velocity profile.
