Abstract
A method for calculating an average phase offset in a two dimensional magnetic recording system includes calculating a phase offset as a difference between a phase of a first signal derived from a first read head and a second phase of a second signal derived from a second read head, correcting for phase wrapping differences between the phase offset and a previous phase offset, determining whether the phase offset is consistent with the previous phase offset, and calculating an average phase offset which includes the phase offset only if it is consistent with the previous phase offset.
