A method for accessing data in an optical disk with a drive. The drive has a memory. The optical disk has data blocks for recording data, and spare blocks for replacing defect data blocks. The method includes reading a predetermined number of spare blocks into the memory,and while reading a defect data block, checking whether a corresponding replacing spare block is stored in the memory. If so, suspending further reading of the spare block. Otherwise, reading the spare block with a predetermined number of other spare blocks into the memory to reduce further reading of spare blocks.
