Abstract: A control system for positioning a magnetic disk transducer head includes a primary carriage which provides large magnitude positioning movements and supports in a ''''piggyback'''' arrangement a low mass secondary carriage which positions the head relative to the primary carriage to provide highly accurate, extremely fast response over small distances on the order of one track width. Improved operating characteristics are obtained to permit increased track density by simultaneously and continuously controlling both carriages in response to a single position error signal with the secondary carriage being biased toward a zero displacement position relative to the primary carriage.
