Abstract
A method of verifying that a disc recording and reproducing apparatus normally analyzes defect management area (DMA) information in a read or write mode, and a test apparatus for performing the method. The method includes operating the recording and reproducing apparatus in a read or write mode, using a test disc with test reference information, and checking whether the recording and reproducing apparatus operates in the read or write mode to verify the DMA information analyzing function of the recording and reproducing apparatus. Accordingly, a DMA information analyzing function of the disc recording and reproducing apparatus in the read or write mode can be tested.
Claims44
A method of verifying a defect management area (DMA) information analyzing function of a recording and reproducing apparatus which records information on or reproduces information from a disc with DMA information, the method comprising:
- operating the recording and reproducing apparatus in a read or write mode, using a test disc with test reference information;
- and
- checking whether the recording and reproducing apparatus operates in the read or write mode to verify the DMA information analyzing function of the recording and reproducing apparatus.
An apparatus for testing a defect management area (DMA) information analyzing function of a recording and reproducing apparatus which records information on or reproduces information from a disc with DMA information, the apparatus comprising:
- a test disc with test reference information;
- and
- a drive to be tested translating the DMA information recorded on the test disc when the test disc is loaded thereinto and attempting to perform a process in a read or write mode.
A method of verifying a defect management area (DMA) information analyzing function of a recording and reproducing apparatus which records information on or reproduces information from a disc with DMA information, the method comprising:
- storing test information having an incorrect start logical sector number of at least one zone on a test disc;
- and
- determining whether the recording and reproducing apparatus performs a process in a reading or writing mode on the test disc.
An apparatus for verifying a defect management area (DMA) information analyzing function of a recording and reproducing apparatus which records information on or reproduces information from a disc with DMA information, the apparatus comprising:
- a reference drive storing test information having an incorrect start logical sector number of at least one zone on a test disc;
- wherein the test disc is usable to determine whether the recording and reproducing apparatus performs a process in a reading or writing mode on the test disc.
A recording and reproducing apparatus verified according to the process of:
- storing test information having an incorrect start logical sector number of at least one zone on a test disc;
- and
- determining whether the recording and reproducing apparatus performs a process in a reading or writing mode on the test disc.
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:
- storing test information having an incorrect start logical sector number of at least one zone on a test disc;
- and
- determining whether the recording and reproducing apparatus performs a process in a reading or writing mode on the test disc.
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
- storing test information having an incorrect start logical sector number of at least one zone on a test disc;
- and
- determining whether the recording and reproducing apparatus performs a process in a reading or writing mode on the test disc.
