Method of verifying defect management area information of optical disc upon initialization without certification and test apparatus for performing the same

A method of verifying whether a recording and reproducing apparatus reads and processes defect management area (DMA) information properly, comprising:

• performing initialization without certification on a test disc containing predetermined known physical defect information, to generate test information;
• and
• comparing the test information with reference test information to determine a verification of the recording and reproducing apparatus,
• wherein
• the performing of the initialization without certification comprises:
• having the recording and reproducing apparatus perform the initialization without certification on the test disc, to generate a disc with the DMA information, and
• reading only the DMA information from the disc using a reference drive, to generate a DMA mirror file as the test information, and
• the reference test information is a reference DMA mirror file.

A method of verifying whether a recording and reproducing apparatus reads and processes defect management area (DMA) information properly, comprising:

• performing initialization without certification on a test disc containing predetermined known physical defect information, to generate test information;
• and
• comparing the test information with reference test information to determine a verification of the recording and reproducing apparatus,
• wherein the comparing comprises checking a structure of a DMA, a disc definition structure (DDS) of the DMA, a primary defect list (PDL) structure and a secondary list (SDL) structure of the DMA, which form the test information.

A method of verifying whether a recording and reproducing apparatus reads and processes defect management area (DMA) information properly, comprising:

• performing certification without reinitialization on a test disc with respect to which the reproducing and recording apparatus generated the DMA information, the test disc containing predetermined known physical defects;
• generating test information from the generated DMA information;
• and
• comparing the test information with reference test information to determine a verification of the recording and reproducing apparatus.
