Abstract
A defect management method applied in an optical disc drive for managing defect information of an optical disc is disclosed. The optical disc drive saves a plurality of defect tables comprising at least a first defect table and a second defect table. The first defect table records a plurality of first defect entries and the second defect table records a plurality of second defect entries. The method includes appending an adaptive defect entry comprising a new defect information corresponding to a new defect into a new defect table, a data structure of the adaptive defect entry conforming to a data structure of at least one of the defect entries recorded in the defect tables; and merging the adaptive defect entries into one of the defect tables saved in the optical disc drive when a condition is met.
