A disc defect management method and apparatus using a defect management area that can be updated, and a write once disc incorporating the method. A data area is disposed between a lead-in area and a lead-out area. The disc includes a defect management area (DMA) that is present in at least one of the lead-in area or the lead-out area, wherein defect information and defect management information are repeatedly recorded in the DMA according to a recording operation. Accordingly, the disc defect management method and apparatus enable effective use of the defect management area. The method is also applicable to a multi layer disc having a user data area on each layer. The defect information and the defect management information for an individual defect may include cumulative defect information and defect management information related to previously identified defects.
