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

A method of verifying whether defect management area (DMA) information is properly generated or updated in a recording and reproducing apparatus which records or reproduces information on or from an optical disc with the DMA information, the method comprising:

• setting a test reference according to a reinitialization with certification mode test mode;
• generating test information from the DMA information, which is generated or updated by the recording and reproducing apparatus, according to the reinitialization with certification test mode;
• and
• executing a test for verifying the test information using the test reference in the reinitialization test mode.

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

• preparing a test disc having known physical defects and a test reference DMA mirror file;
• generating test information based on having the recording and reproducing apparatus perform reinitialization with certification on 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:

• performing reinitialization with certification on a test disc having known physical defects and a test reference DMA mirror file 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:

• performing reinitialization with certification on a test disc containing known physical defects and a test reference DMA mirror file 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:

• performing reinitialization with certification on a test disc containing known physical defects and a test reference DMA mirror file 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 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:
• performing reinitialization with certification on a test disc containing predetermined defect information and test reference DMA information using the recording and reproducing 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
• performing reinitialization with certification on a test disc containing predetermined defect information and test reference DMA information using the recording and reproducing apparatus to generate test information, and
• comparing the test information with reference test information to determine the verification of the recording and reproducing apparatus.

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

• a light source to emit a light;
• a focusing element to focus the light onto the optical disc for recording and reproducing the information;
• and
• a controller to control said light source and to update and generate defect management area information after performing reinitialization with certification on the optical disc so that the defect management information is compliant with a standard.
