Abstract: A recording medium of writable once type, and a method and apparatus for managing a defective area on the recording medium are provided. The method includes detecting an existence of a defective area within a data area of the recording medium once data are written onto the data area in a data writing operation, writing data written in the defective area onto another area of the data user if the defective area is detected, and writing, onto at least one defect management area on the recording medium, defect management information associated with the defective area.

Abstract: A method for managing a defective area of a write-once optical recording medium, and an optical recording medium using the same, are provided. The method includes steps of firstly writing replacement data in a predetermined area, the replacement data corresponding to a defective area detected during a data reproduction operation; secondly writing locator information in the predetermined area, the locator information indicating respective positions of the defective area and the corresponding replacement data; and thirdly writing a supplementary access pointer in a lead-in area, the access pointer for accessing the locator information written in the predetermined area. The predetermined area, which may be located inside or outside the data area, stores supplementary defect list information enabling data read operations when defective areas are newly detected by a host after recording data on a write-once type disc such as a BD-WO disc.

Abstract: Optical recording medium having an indication of a recording capacity, and method for indicating a recording capacity of an optical recording medium facilitates recording or reproducing of an accurate amount of data by indicating the initial recording capacity determined by default and the varied recording capacity by additional allocation of the spare area and the like on particular area of the optical recording medium, and conducting the data writing or reading with reference to the initial recording capacity or the varied recording capacity depending on a state of variation of the recording capacity.

Abstract: A defective area on a write-once type optical recording medium, e.g., such as a BD-WO, is effectively managed with a method that can efficiently replace and/or record data that has been recorded in a defective area of the disc, e.g., in a spare area of a data area of the BD-WO. During the reproduction of data, the data that has been recorded and replaced can be read out and reproduced from an area other than a spare area. New TDFL information may be recorded cumulatively with the previous TDFL information as defect management information for the defective area, or repeatedly recorded at least twice in a certain recording region, e.g., a recording region chosen from a lead-in area, the data area, and a lead-out area, so that the temporary defect list information can be accurately and reliably secured.

Abstract: A recording medium of writable once type, and a method and apparatus for managing a defective area on the recording medium are provided. The method includes detecting an existence of a defective area within a data area of the recording medium once data are written onto the data area in a data writing operation; writing data written in the defective area onto a spare area of the data area if the defective area is detected; writing temporary management information pertaining to the defective area, onto a temporary management area on the recording medium; and writing access information for accessing the temporary management information, onto a reserved area on the recording medium.

Abstract: 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.

Abstract: A recording medium and a spare area management method for an optical recording medium are provided. The spare area management method utilizes an identification information to indicate whether a primary spare area is full or a supplementary spare area has been assigned or extended, as necessary. The spare area management method improves the performance of the driver by replacing a defective block with a spare block nearer to the defective block.

Abstract: Device and method for recording a data on an optical recording medium, the device including a controller for transmitting a data to be written, if the data to be written is produced, together with a control signal, determining that a data in a block of the sector the data to be written is valid if the data to be written is a sector unit data, marking a result of the determination as identification information in the control signal, and transmitting the identification information, and a data writing part for identifying the identification information in the control signal from the controller, and writing the data from the controller in the sector designated by the control signal directly, if the identification information indicates that the data in the block having the sector the data to be written therein is not valid, thereby reducing data writing failure caused by failure of reading data in sectors in a block other than the sector the data to be written therein, and enhancing a system performance in writing

Abstract: 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.

Abstract: A method and device for searching a first available good spare block from an optical recording medium is disclosed. In the present invention, a first good block in a spare area is determined to be the first available spare block when there is at least one entry to a SDL without an entry of a replacement block assignment. Therefore, the present invention prevents searching a wrong replacement block when SDL entries without replacement block assignment are present.
