    摘要: A recording/reproducing apparatus is configured to record a replacement block by logical overwrite (LOW) for updating data recorded on an information storage medium in a first area of the medium, record a replacement block for replacing a defect block generated on the medium in a second area of the medium, and record a second replacement block for replacement by defect of a first replacement block in the second area if the defect is detected while the first replacement block is being recorded in the first area to perform the logical overwrite of an original block recorded in a predetermined area of the medium, generate a defect list (DFL) entry including location information of the original block and location information of the second replacement block in order to indicate the replacement state, and move location information of the first replacement block in the second replacement block.

    摘要: An error correction block having an extended format compatible with a standardized format of a conventional error correction block, a method and apparatus for generating the error correction block, and a method of correcting an error using the error correction block. The method of generating an error correction block includes adding extra parity information for error correction to input data which is of a smaller size than main data of a standardized reference format, thereby generating an extra error correction block which is the same size as the main data, and generating an error correction block complying with the reference format using the extra error correction block as the main data.

    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.
