METHOD FOR IDENTIFYING DEFECT MANAGEMENT AREA INFORMATION OF OPTICAL DISC UPON INITIALIZATION WITHOUT CERTIFICATION AND TEST APPARATUS FOR PERFORMING THE SAME

摘要

PURPOSE: A method for identifying defect management area information of an optical disc upon initialization without certification and a test apparatus for performing the same are provided to identify whether defect management area information is exactly generated during initialization without certification. CONSTITUTION: A test type disc(11) is a disc having only known physical defects on a predetermined position of a blank disc. But, the test type disc(11) may be treated as a test disc on a simple blank disc wherein no data are recorded. A drive(110) to be tested performs initialization without certification with respect to the test type disc(11) to generate DMA information and record the generated DMA information on the test type disc. An initialized test type disc(12) without certification provided from the drive(110) is mounted on a modified drive(120) which can read the DMA information. The modified drive(120) is called as a reference drive which is a test-only drive manufactured by a manufacturer. The modified drive(120) reads only the DMA information recorded on the initialized test type disc(12) without certification and generates a DMA mirror file(13) for the initialized test type disc without certification on a file system.
