A servo system for detecting and demodulating servo data is disclosed. In illustrated aspects, a demodulation circuit or portion includes a correlator component configured to output a correlation of a sequence of equalized channel samples with a sequence of correlator weight derived based on at least one mapped channel sequence. A decision component, for example a threshold detector uses the correlation results to output a data bit symbol based upon the correlation of the sequence of equalized channel samples to the at least one mapped channel sequence.
