Abstract: Disclosed is a defect detection apparatus of an optical disk drive. The optical disc drive records a set of first data onto at least one data unit of an optical disc. The defect detection apparatus comprises an error detector and a defect verification unit. The error detector receives the set of first data, being recorded and the set of second data derived from the data unit of the optical disc, and then compares the set of first data with that of second data to generate error information of the set of second data. The defect verification unit determines whether the data unit is defective according to the error information. The object that the defect detection apparatus of the invention performs verification for can be a sector, an ECC Block or a cluster. The error detector can be a channel bit error detector, a byte error detector or a frame error detector.
