The channel characteristics of magnetic-disk storage devices vary with track radius. An adaptive three-tap transversal equalizer that compensates these variations for systems using partial-response signaling is presented. The equalizer coefficients are updated by applying a procedure that is related...http://www.google.fr/patents/US5060088?utm_source=gb-gplus-shareBrevet US5060088 - Adaptive equalization for recording systems using partial-response signaling
