Method of verifying defect management area information of disc and test apparatus for performing the same |
摘要 |
A method of verifying that a disc recording and reproducing apparatus normally generates or updates defect management area (DMA) information in a supplementary spare area extension mode, and a test apparatus therefore. The method includes extending the supplementary spare area of a test disc in the recording and reproducing apparatus using the test disc with test reference information and generating test information from the test disc; and comparing reference information expected from the test reference information with the test information and providing the result of verification of the test information. Accordingly, a DMA information generation or updating function of the recording and reproducing apparatus upon the extension of the supplementary spare area can be easily verified.
