    摘要: The embodiment includes a data replacing area secured in preparation for a defect in a data area, a current DMA set for recording defect management information of a replacement process using the data replacing area, a plurality of unused DMA set areas for replacing a current DMA set, a current DMA managerset area for the current DMA manager set which manages the replacement process using the plurality of unused DMA set, and a plurality of unused DMA manager set areas for replacing the current DMA manager set area. In the unused DMA manager set, there are provided a manager data area describing FFh for showing it is unused, and an identifier area describing 0010h for showing an available manager set.

    摘要: There is provided an information management apparatus which can make it impossible to read out data recorded on a write-once type recordable optical disk as required and the usefulness thereof is enhanced. When recorded data is destroyed on the write-once type recordable optical disk, data modulated by a modulation system of the same run length restriction as run length restriction of a modulation system used for recording data is overwritten and recorded, data is overwritten and recorded by use of patterns in which the frequency of occurrence of spaces of the longest code is higher than the frequency of occurrence of the modulation system used for recording data, or data is overwritten and recorded by use of successive patterns of the shortest code in the run length restriction of the modulation system used for recording data.
