The invention relates to an optical disc of write once type, method and apparatus for managing defect information on the optical disc. An optical disc of write once type, a method and an apparatus of managing defect information on the optical disc of write once type, e.g., a BD-WO, are provided with a temporary defect management area (TDMA). The method includes preparing the temporary defect management area (TDMA) in which a temporary defect list (TDFL) is recorded as defect management information for managing a defective area on the optical disc, recording the most recent temporary defect list cumulatively with the previous temporary defect list in the temporary defect management area, and recording position information for indicating a position of the most recent temporary defect list in the temporary defect management area along with the temporary defect list to more effectively manage the temporary defect list.
