    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 method of overwriting data in a write-once information storage medium and a data recording and/or reproducing apparatus provided for overwriting data in such a write-once information storage medium. 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 of managing defects considering compatibility with a rewritable disc, a reproducing and/or recording apparatus implementing the same, a write-once recording medium therefore, and a medium including computer readable code controlling the implementation of defect management. The method includes providing a plurality of temporary defect management areas on the write-once recording medium; performing defect management using the plurality of temporary defect management areas; and when one among the plurality of temporary defect management areas is exhausted, writing full flag information indicating that the one temporary defect management area is exhausted to at least one among remaining temporary defect management areas. Accordingly, defect management can be efficiently performed.
