Abstract: A method for recording data on an optical recording medium includes the step of receiving data to be written and control data. The control data includes status information to indicate whether or not an other sector within a block in which a sector is included is valid. The data is written in an other sector within the block. The method further includes determining whether to perform an error certification process based on the control data, and writing the data based on the result of determining step.

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: An optical recording medium and a method for recording information to indicate a recording capacity of the recording medium, are provided. The method includes recording information to indicate a varied recording capacity on a particular area of the optical recording medium, if an initial recording capacity of the optical recording medium is varied based upon at least one of an assignment and a variance of a spare area for a defect management, the spare area being assigned to an inner area and/or an outer area of the optical recording medium, or being varied toward an inner direction with respect to an outer position.

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.
