Abstract
An apparatus and method to read and/or write information from and/or to a moving magnetic tape comprising one or more servo edges using a tape head comprising (N) servo sensors. Bach servo edge comprises an interface between a first recorded signal and a second recorded signal, where each of the (N) servo sensors detects that first recorded signal and that second recorded signal. The method calculates (N) target PES signals and provides (N) measured PES signals. Using the target and the measured PES signals, the method forms (N) weighted PES signals and averages those (N) weighted PES signals to form a Composite PES signal. That Composite PES signal is used to position the tape head.
