1. A data processing system, the data processing system comprising:
a multi-pass defect detector circuit including: a defect quality characterization circuit operable to determine a defect amplitude based upon two or more accesses of a data set from a location on a medium identified as potentially defective; and a threshold comparison circuit operable to compare the defect amplitude with a threshold value to yield a defect indication.
