摘要: A disk drive is disclosed that enables defect margining during disk drive burn-in testing. The disk drive comprises: a disk comprising a plurality of tracks; a head actuated over the disk; and a processor. The processor is configured to: perform disk drive burn-in testing to detect media defects; generate an initial defect list based upon detected media defects for sectors; generate an extended defect list that includes detected media defects and extended defect margins from the detected media defects; and utilize the extended defect list for burn-in, wherein a spare area of the disk allows for the detected media defects and the extended defect margins.
