    Abstract: The invention relates to an adaptive digital servo system which comprises a track position profile sequencer for generating a sequence of binary position signals, a track correction profile sequencer for generating a sequence of binary correction signals, where there exists a correction signal in the track correction profile sequencer for each position signal in the track position profile sequencer, a present position decoder for generating a binary signal indicative of the actual position of the member being moved and controlled by the servo system, an error generator for comparing the commanded position signal from the track position profile sequencer and the actual position signal to generate a binary error signal, a combination means for combining the generated error signal with the correction signal associated with the position signal used to generate the error signal to form a controlled signal for controlling the actuator of the servo system, a track correction profile generator for extracting the repeatable error component from the error signals being generated by the error generator, and updating means for modifying the correction signals associated with the position signals presently controlling the servo system by a correction signal generated from the repeatable error component extracted from the error signals by the track corrector profile generator.
