  • Publication number: 20090259891
    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.

  • Publication number: 20080186823
    Abstract: A defect detection system, defect detection method and disc verification method for rewritable optical discs are provided A demodulator reads an optical disc to obtain a plurality of sectors corresponding to an ECC block along with parity inner (PI) and parity outer (PO) codes. A sector detector, coupled to the demodulator, decodes the PI codes to obtain defect information of the sectors. A memory is coupled to the sector detector, storing contents and defect information of the sectors. An ECC block detector decodes the PO codes, and determines defectiveness of the ECC block based on the defect information and the PO codes. A processor controls the PI and PO decoding procedures and a further PDL/SDL update procedure.
