Abstract:
A method of determining a transducer position in relation to a media surface, comprising the steps of:sensing positioning information on the media; measuring a position error signal from the sensed positioning information wherein the position error signal includes first and second position signal components; accessing stored information describing a non-linear relationship between the measured position error signal (PESmeasured) and the transducer position, wherein the non-linear relationship is described by a function p=Æ’(PESmeasured) wherein p is the read transducer position and the function p=Æ’(PESmeasured) is constrained so that Æ’(a)=&agr; where &agr; corresponds to a stitch point, applying the stored relationship to the measured position error signal (PESmeasured) to produce a corrected position error signal; and determining the transducer position from the corrected position error signal.
