1. A data processing system, the system comprising:
a sync mark detection and forcing circuit operable to:
receive an input data set;query the input data set to identify an actual sync mark; andforce a proxy sync mark where the actual sync mark is not identified; andre-force the proxy sync mark based upon an offset; a data processing circuit operable to:
apply a data processing algorithm to the input data set aligned using the forced proxy sync mark to yield a processed output; andre-apply the data processing algorithm to the input data set aligned using the re-forced proxy sync mark to yield a re-processed output; and a reverse sync mark derivation circuit operable to:
correlate a portion of the processed output with a corresponding portion of the input data set to yield a true sync location; anda calculate a difference between the true sync location and the location of the forced sync mark to yield the offset.
