Patent ID: 7441149

Claim:
A method for managing a defective data block of a recording medium, the method comprising: (a) determining whether there is an available replacement block in a spare area and a found defective data block is controlled by a linear replacement algorithm; (b) managing a defective data block based on the determination, such that the defective data block is replaced with the replacement block of the spare area if there is the available replacement block and the found defective data block is controlled by the linear replacement algorithm while the defective data block is not replaced with the replacement block of the spare area if the found defective data block is not controlled by the linear replacement algorithm; and (c) recording at least one of a first defect list and a second defect list to a specific area of the recording medium as a result of the step (b), wherein the first defect list includes first position information for specifying the location of the defective data block, second position information for specifying the location of the replacement block and identification information for specifying that the defective data block is replaced, and the second defect list includes first position information for specifying the location of the defective data block and identification information for specifying that the defective data block is not replaced.
