Method of verifying defect management area information of optical disc upon initialization with certification and test apparatus for performing the same
First Claim
1. A method of verifying that defect management area (DMA) information is properly generated in a recording and reproducing apparatus which records or reproduces information on or from an optical disc with DMA information, the method comprising:
- generating as test information, defect management information, which is generated after performing initialization with certification on a test disc obtained by making known physical defects on a blank disc; and
verifying the test information using reference test information for the initialization with certification to provide a test result.

Abstract
A method of verifying defect management area (DMA) information of an optical disc upon initialization with certification, and a test apparatus for performing the same. The method includes generating, as test information, defect management information, which is generated after performing initialization with certification on a test disc, which is obtained by making known physical defects on a blank disc, and verifying the test information using reference test information for initialization with certification to provide the test result. Accordingly, it can be easily verified that a recording and reproducing apparatus properly translates and processes DMA information which is generated after initialization with certification, using a test disc with known physical defects.
