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： Method for formatting, and managing a defective area of, a rewritable optical recording medium when a secondary defect list (SDL) is converted into a primary defect list (PDL) without certification by converting only sector numbers of first sectors of the defective blocks listed on the SDL into the PDL. If the defective sector thus listed of the PDL is encountered during writing/reading thereafter, a block (=16 sectors) containing the defective sector is subjected to slipping replacement.

摘要： A method for real time recording and playback of data to and from an optical recording medium, and a method for managing a file thereof is disclosed. In the present invention, the host controls real time data writing by providing a signal requesting for information on a defective area to the device for recording/playback of data to/from an optical disk before providing a write command. Accordingly, the write command is generated such that data is not written on the defective areas, based upon the returned information on the defective area. Alternatively, the host may first provide a write command to the device for recording/playback of data to/from an optical disk, upon which information on defective areas is returned. Thus, the host generates and provides a new write command such that data is not written on a defective area based upon the returned information on the defective area.
