Abstract
A method for accessing data of an optical disk with a disk drive. The drive includes a memory; the optical disk has a plurality of data blocks for recording data and a plurality of spare blocks for replacing defect data blocks. While reading data recorded on the optical disk, a predetermined number of data blocks are read, then spare blocks for replacing defect data blocks among the predetermined number of data blocks are read. While writing data onto the optical disk, a predetermined number of data blocks are written, then data written in defect blocks among the predetermined number of defect blocks are written in corresponding spare blocks. The predetermined numbers are determined by a memory capacity of the memory, or a progress of the reading or writing.
