Abstract
A write-once recording medium structure and an apparatus and method for recording final management information on the recording medium, are provided. The recording medium includes a temporary defect management area (TDMA) and a defect management area (DMA). The method includes transferring information recorded in the TDMA to the DMA of the recording medium and recording the transferred information in the DMA as final management information. The final management information includes at least one defect list and either space bit map information or sequential recording range information. The position information on one or all valid defect lists is recorded in the DMA.
