Abstract
In a method for determining defective blocks of an optical disc, a defect-detection procedure for each block of the optical disc is performed. After the defect-detection procedure, a preliminary defective group of the optical disc is realized. Subsequently, the track number between two selected defective blocks of the preliminary defective group are detected. When the track number is less than a predetermined number, the blocks lying in a linear region including the two selected blocks are defined as defective blocks in addition to all defective blocks included in the preliminary defective group.
