Method of verifying defect management area information of optical disc

摘要

A method of verifying the defect management area (DMA) information of an optical disc. The method verifies that DMA information is properly generated or updated after a recording and reproducing apparatus, which records or reproduces information on or from an optical disc with DMA information, performs a process in a test mode for testing the generation or update of DMA information. The method includes reading the generated or updated DMA information and verifying the generated or updated DMA information using reference DMA information which is predetermined for the test mode and providing the verified result. Accordingly, it is easily verified that the recording and reproducing apparatus exactly generates or updates defect information by performing various test modes using different test discs having predetermined defect information, which has no relation with actual defects, instead of using a disc having the actual defects.
