Abstract
An apparatus for detecting media flaws includes an envelope based media defect detector operable to identify a media defect based on an envelope of an input signal, a periodic pattern detector operable to determine whether the input signal comprises a data pattern, and a media flaw signal generation circuit operable to indicate a media defect when the envelope based media defect detector identifies the media defect and the periodic pattern detector determines that the input signal does not comprise the data pattern.
