摘要： An information recording medium, and a recording/reproducing apparatus and a recording/reproducing method for the recording medium. Original data is sequentially updated by replacing an original recording block with one or more replacement recording blocks. A replacement recording block includes at least one of an original address field indicating a location of the original recording block or a previous address field indicating a location of an immediately previous recording block. Replacement information is effectively recovered in a system where a replacement for logical overwriting (LOW) occurs in either a spare area and a user data area by reference to the address fields in each replacement recording block.

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 reproducing a recording medium having finalized recorded data. Data is read from the recording medium and a determination is made whether the recording medium is further recordable based on whether a temporary defect management area includes repetitions of a predetermined value or based on whether another predetermined value is recorded in response to a finalization command previously recorded.

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 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.
