Method of verifying defect management area information of optical disc and apparatus for performing the same

A method of verifying whether a recording and reproducing apparatus properly translates and processes defect information, the method comprising:

• preparing a test disc using a defect management area (DMA) mirror file with pre-fixed defect information unrelated to actual defects on the test disc;
• generating test information based on having the recording and reproducing apparatus process the test disc;
• and
• conducting a verification test on the test information.

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

• processing a test disc containing predetermined defect information which does not have any relation with actual defects on the test disc using the reproducing and recording apparatus to generate the DMA information;
• 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.

DMA information which is properly generated by a recording and reproducing apparatus using the process of:

• processing a test disc containing predetermined defect information which does not have any relation with actual defects on the test disc using the reproducing and recording apparatus to generate the DMA information;
• 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.

A recording and reproducing apparatus verified according to the process of:

• processing a test disc containing predetermined defect information which does not have any relation with actual defects on the test disc using the reproducing and recording apparatus to generate DMA information;
• 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.

A method of manufacturing a compliant recording and reproducing apparatus, comprising:

• manufacturing an uncertified recording and reproducing apparatus that updates and generates defect management area (DMA) information;
• and
• verifying whether the uncertified recording and reproducing apparatus is compliant with a standard, said verifying comprising:
• using a test disc containing predetermined defect information which does not have any relation with actual defects on the test disc and the reproducing and recording apparatus to generate test information, and comparing the test information with reference test information to determine a verification of the recording and reproducing apparatus, the verification indicating that the uncertified recording and reproducing apparatus is compliant with the standard.

A disc recording and reproducing apparatus for recording and reproducing information on an optical disc, comprising:

• a light source to emit a light;
• a focusing element to focus the light onto the optical disc to record and reproduce the information;
• and
• a controller to control said light source, said controller being verified to update and generate defect management area (DMA) information by using a test disc containing predetermined defect information which does not have any relation with actual defects on the test disc and the reproducing and recording apparatus to generate test information, and comparing the test information with reference test information to determine the verification of the recording and reproducing apparatus.
