摘要： The present invention relates to an optical recording medium and optical recording medium record/playback apparatus and method, for managing defective areas in a rewritable optical recording medium. Particularly, the present invention adds a linear replacement control (LRC) bit to a secondary defective list (SDL) entry to discriminate a defective block information that is listed at the SDL entry according to a linear replacement algorithm from a defective block information that is listed at the SDL entry according to a skipping algorithm. This allows the optical recording medium record/playback apparatus to transmit correct information to a host. Furthermore, when a defective block requiring a new replacement block is found while recording or playing back data when the spare area is full, instead of carrying out the linear replacement, the LRC bit is set in the SDL entry along with the location information of the defective block to indicate that the corresponding SDL entry was made when the spare area was full, whereby data is not written in the defective block or data of the defective block is not read when rewriting or reproducing the data afterward. Consequently, the present invention can provide efficient management over the optical recording medium.

摘要： A method and apparatus for managing defect areas of a rewritable optical recording medium. Upon receiving a write or read command from a host, the defect areas management apparatus decodes a PID of a position being currently traced by an optical pickup, generates the resultant physical sector number of the current position and compares it with a physical sector number of a defect area stored in a DMA storage unit. If the two physical sector numbers are the same, the defect areas management apparatus does not write or read data on a sector of the position traced by the optical pickup. Therefore, the defect areas management apparatus is capable of efficiently managing defect areas of the optical recording medium.

摘要： An optical recording medium record/playback apparatus manages defective areas in a rewritable optical recording medium. A linear replacement control (LRC) bit is added to a secondary defective list (SDL) entry to discriminate defective block information listed in the SDL entry, according to a linear replacement algorithm, from defective block information listed at the SDL entry, according to a skipping algorithm. This allows the apparatus to transmit correct information to a host. When a defective block requiring a new replacement block is found during recording or playing back data and the spare area is full, instead of carrying out the linear replacement, the LRC bit is set in the SDL entry, along with the location information of the defective block. This indicates that the SDL entry was made when the spare area was full. Thus, data is not written in, or read from, the defective block.
