    Abstract: Replacement data for updating data recorded on an information storage medium is recorded in an area for logical overwrite (LOW) replacement; replacement data for replacing a defect generated on the medium is recorded in an area for defect replacement; and, if a defect is generated in an original block recorded in a predetermined area of the medium during a read-modify-write (RMW) process for a LOW for at least partial data of an original block, a replacement block replacing the original block is recorded in the area for LOW replacement and a defect list (DFL) entry including location information of the original block and location information of the replacement block is generated to indicate the replacement state.

    Abstract: 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.

    Abstract translation: 在一次写入信息存储介质中重写数据的方法以及用于重写这种一次写入信息存储介质中的数据的数据记录和/或再现装置。 在数据重写方法中，发出在已经记录数据的一次写入信息存储介质的第一区域中覆盖新数据的命令。 然后，将第一区域视为缺陷区域，并将新数据记录在第二区域中。 此后，更新的缺陷管理信息（包括关于第一和第二区域的位置的信息）被记录在一次写入信息存储介质中。 因此，可以通过使用逻辑重写技术在不能进行物理重写的一次写入信息存储介质中执行重写。 因此，可以改变或更新记录在一次写入信息存储介质中的数据。
