摘要： A method, apparatus and computer readable medium for managing recording medium defects and a defect managed recording medium. The recording medium includes a spare area in which a replacement area, which is a substitute for a defective area of the recording medium, is formed, and a temporary defect management area in which temporary management information that specifies the defective area and the corresponding replacement area is recorded, wherein position information and state information regarding the defective area are recorded in the replacement area. Accordingly, it is possible to restore defect information even if recording medium defect management on the recording medium ended abnormally.

摘要： A method of recording a temporary defect list on a write-once recording medium, a method of reproducing the temporary defect list, an apparatus for recording and/or reproducing the temporary defect list, and the write-once recording medium. The method of recording a temporary defect list for defect management on a write-once recording medium includes recording the temporary defect list, which is created while data is recorded on the write-once recording medium, in at least one cluster of the write-once recording medium, and verifying if a defect is generated in the at least one cluster. Then, the method includes re-recording data originally recorded in a defective cluster in another cluster, and recording pointer information, which indicates a location of the at least one cluster where the temporary defect list is recorded, on the write-once recording medium.

摘要： An apparatus for reproducing a recording medium having a recorded defect management area. The apparatus includes a pickup reading data from a recording medium and a controller controlling the pickup to read data on the recording medium and determining whether the recording medium contains predetermined data, recorded in response to a finalization command, to prevent recording with respect to the recording medium. The controller determines whether an area of a temporary defect management area not having defect management data includes the predetermined data by checking whether the temporary defect management data is filled with repetitions of a predetermined value.
