  • Patent number: 7733751
    Abstract: A method of verifying whether a recording and/or reproducing apparatus that records and/or reproduces a disc having temporary defect management area (TDMA) information properly produces the TDMA information, the method including producing TDMA information produced by performing a recording test according to a series of recording operations based on a scenario using a blank test disc as test information; and providing a result of the recording test by confirming the test information using reference test information for the recording test.
    Type: Grant

  • Patent number: 7617426
    Abstract: A method for verifying whether a recording/reproducing apparatus properly produces disc management information and records the disc management information on a disc includes preparing a test disc; issuing reading commands to a recording/reproducing apparatus to be tested on which the test disc is loaded and verifying the disc in order to verify the reading operation; and issuing recording commands to the recording/reproducing apparatus to be tested on which the test disc is loaded and checking whether a temporary disc management area (TDMA) structure is properly updated on the disc in order to verify the modification operation.
    Type: Grant

  • Patent number: 7490262
    Abstract: A method of determining whether a defect exists on an information storage medium is provided along with a recording/reproducing apparatus using the same. Such a method comprises: seeking a defect entry whose state information indicates that a defect block or a replacement block has been re-initialized without certification from a defect list for managing an information storage medium and including state information of the defect block and state information of the replacement block, wherein the medium includes a spare area for recording the replacement block to replace the defect block occurring in a user data area on the medium; and certifying the defect block or the replacement block registered in the sought defect entry. As a result, defect information can be effectively rearranged for quick re-initialization without certification in order to improve the performance of a drive system.

  • Publication number: 20060288081
    Abstract: An information storage medium including an application for obtaining metadata for a disc library, and an apparatus and a method of obtaining the metadata. The information storage medium includes a network application to download metadata for a disc library from an external server to a reproducing apparatus for reproducing data from the information storage medium, wherein the metadata for a disc library has a structure including identifier information, version information, type information, disc information, and title information and is stored in the reproducing apparatus. Accordingly, the metadata for a disc library can be downloaded from the external server via a network.
