摘要： A write once disc allowing management of a data area, a method of managing the data area of the write once disc, an apparatus recording data on the write once disc, an apparatus and method of reproducing data from a write once disc. The write once disc, includes a lead-in zone, a data area, and a lead-out zone. The write once disc includes a predetermined area storing area allocation information which indicates whether at least one section of the data area is allocated for disc defect management. In the disc and method, area allocation information specifying a structure of the data area is recorded on the disc, thus allowing a recording/reproducing apparatus to recognize the data area structure. Therefore, allocating areas, such as a spare area, for disc defect management other than an area for storing user data, to the data area is possible. The allocation of the areas for disc defect management to the data area enables effective use of the write once disc.

摘要： A write-once recording medium preserving a data recording status of the write-once recording medium, a method of preserving the data recording status of a write-once recording medium, a medium including computer readable code for the same, and a recording and/or reproducing apparatus therefor. In the method of preserving the data recording status of a write-once recording medium, first, data is recorded on the write-once recording medium. Next, recording-status data, representing occupied areas, is produced and recorded in a temporary defect management area allocated in the write-once recording medium. Thereafter, a finalization command is received to preserve the data-recording status of the recording medium. Then, in response to the finalization command, predetermined data is recorded in a temporary defect management area to prevent further data recording on the write-once recording medium. Accordingly, the data recording status of the finalized write-once recording medium can be preserved.

摘要： A method of overwriting data in a write-once information storage medium and a data recording and/or reproducing apparatus therefor. In the data overwriting method, a command to overwrite new data in a first area of the write-once information storage medium where data has already been recorded is issued. Then, the first area is considered as a defective area, and the new data is recorded in a second area. Thereafter, updated defect management information, including information about the locations of the first and second areas, is recorded in the write-once information storage medium. Accordingly, overwriting can be performed in write-once information storage media, which is incapable of physical overwriting, by using a logical overwriting technique. Thus, data recorded in the write-once information storage medium may be changed or updated.

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.
