Abstract
Nonlinearities in the interaction between a servo read head and a servo track are considered to more accurately determine the position error or offset between the servo read head and the servo track. A position error expression is determined based on a track profile for the servo read head. A servo track signal is generated by reading a servo track with the servo read head. The position error is determined based on the servo track signal and the position error expression.
