Abstract
A novel track following method has been proposed, by which the head´s position error signal (PES) can be directly extracted from data sequences encoded by a modified Group Inter-Track Orthogonal Coding (GITOC). One of the advantages of this new method is that the PES is continuous. A continuous PES extracted from data sequences makes a precise track following on very narrow tracks possible. For this reason, this novel data servo method has potential applications in submicron trackwidth servo. The principle of this new method has been confirmed on a longitudinal magnetic recording system
