A servo compensation processor includes an input that receives samples of a waveform generated from a servo track, the servo track including servo data and synchronization symbols. A peak estimator estimates a first location of a peak amplitude of the waveform. A phase determiner determines a sampling phase based on a first number of the samples between one of the synchronization symbols and a first predetermined one of the samples. A compensator determines a compensation amount based on a compensation curve and the sampling phase. A location estimator determines a second location of the peak amplitude based on the first location and the compensation amount. A location determiner determines a center location of the servo track based on the second location.
