Abstract

A method of verifying the defect management area (DMA) information of a recordable and reproducible optical disc, and a test apparatus for performing the same.
The method of verifying the DMA information includes selecting one among a plurality of test modes for verifying DMA information, setting a test reference according to the selected mode, generating test information from the DMA information, which is generated or updated by a recording and reproducing apparatus to be tested, according to the verification test mode, and executing the test for verifying the test information using the test reference in the selected mode Accordingly, it is easily verified that a recording and reproducing apparatus properly translates and processes defect information, by using a different test disc, which is made using a mirror file with pre-fixed defect information which is not related to actual defects on a disc, depending on the DMA information verification test modes.
