摘要： A disc having an updatable defect management area used by an apparatus for managing defects on the disc, the disc including a user data area which includes user data, a spare area that is a substitute area for a defect existing in the user data area, and an area in which are recorded an address of data that is last recorded in the user data area and an address of a replacement data recorded in the spare area. Accordingly, the disc defect management method and apparatus are applicable to a recordable disc such as a write-once disc while effectively using a defect management area of the disc.

摘要： A method of recording a temporary defect list on a write-once recording medium, a method of reproducing the temporary defect list, an apparatus for recording and/or reproducing the temporary defect list, and the write-once recording medium. The method of recording a temporary defect list for defect management on a write-once recording medium includes recording the temporary defect list, which is created while data is recorded on the write-once recording medium, in at least one cluster of the write-once recording medium, and verifying if a defect is generated in the at least one cluster. Then, the method includes re-recording data originally recorded in a defective cluster in another cluster, and recording pointer information, which indicates a location of the at least one cluster where the temporary defect list is recorded, on the write-once recording medium.

摘要： An apparatus for reproducing a recording medium having a recorded defect management area. The apparatus includes a pickup reading data from a recording medium and a controller controlling the pickup to read data on the recording medium and determining whether the recording medium contains predetermined data, recorded in response to a finalization command, to prevent recording with respect to the recording medium. The controller determines whether an area of a temporary defect management area not having defect management data includes the predetermined data by checking whether the temporary defect management data is filled with repetitions of a predetermined value.

摘要： An error correction block having an extended format compatible with a standardized format of a conventional error correction block, a method and apparatus for generating the error correction block, and a method of correcting an error using the error correction block. The method of generating an error correction block includes adding extra parity information for error correction to input data which is of a smaller size than main data of a standardized reference format, thereby generating an extra error correction block which is the same size as the main data, and generating an error correction block complying with the reference format using the extra error correction block as the main data.
