ABSTRACT:
A method for replacing a defective block with a good block in an optical disk allows data recording operations to be effectively performed. The method temporarily stores data that would have otherwise been recorded in a defective area of an optical disc in a temporary buffer. The method then stores the data in the temporary buffer in a spare area of the optical disc after the normal data recording operation is completed, or if the amount of data in the buffer exceeds a predetermined memory capacity. The method can continuously and quickly perform a general data recording operation, effectively avoid a system load increase due to frequent track movements on an optical disc, and appropriately record real-time data without the loss of data.
