摘要： A disk drive configured to enable media defect margining during disk testing may comprise a disk comprising a plurality of tracks; a head actuated over the disk; and a processor operable to test media of the disk drive to detect a media defect; estimate a depth of the detected media defect; determine a margining amount based on at least the estimated depth of the detected media defect, and apply the determined margining amount to the detected media defect.
