Method for managing defective area on write-once optical recording medium, and optical recording medium using the same

The write-once recording medium and a method for managing a defective area on the recording medium is provided. An optical disc apparatus for using the recording / reproducing data for an optical disc such as a BD-WO type disc, through the operation of replacement recording the data that has been recorded on the defective area, the data written on the defective area on the disc normal recording or It provides a method for playing. If a fault is detected within a predetermined recording area of ​​the optical disc during the recording operation, the recorded data is being recorded on the spare area corresponding to the defective area is managed. To perform the process, the disc finalization before a valid temporary defect list (TDFL) of the information recorded in the position (write location), and a disc finalization operation is the recording position of the valid defect list (DFL) information in performing (write location) to provide a method of selectively searching a. And the TDFL information includes one or more defective area data location information (locators), indicating that becomes recorded in the assigned recording area, and the detected defective area. Recording position information (write location information) and identification information (identification information) is to a record within a defect management area (DMA) within, the disc definition to be written with the DFL information structure (DDS) allocated in the disc lead-in area, the disc It enables a selective search the DFL information after the finalization.
