1. A data processing system, the data processing system comprising:
a data detector circuit operable to apply a data detection algorithm to a symbol based data set guided by a decoded output to yield a symbol based detected output; a defect detector circuit including:
a data pre-processing circuit operable to pre-process the symbol based detected output to yield a pre-processed output; anda binary data detection circuit operable to provide a defect indicator corresponding to a probable defect identified based on the pre-processed output; and a data decoder circuit operable to apply a data decode algorithm to a decoder input derived from the detected output modified based on the defect indicator to update the decoded output.
