    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.

    摘要: When an information recording and reproducing apparatus records pieces of user data on a write-once optical disk on which information can additionally be written, the information recording and reproducing apparatus performs a closing process so that the pieces of user data can also be reproduced with the reproduction-only apparatus. The closing process includes recording final recording position information indicating an end position of the recorded information in the outside of the user data. Then, in the case where user data is additionally written, the final recording position information is erased using a predetermined pattern through the closing process, and the new final recording position information is recorded in a rear position of the user data.

    摘要: In order to select the latest defect management information, the latest selection information first is selected by searching a plurality of selection information areas for a currently active selection information area in which the latest selection information is recorded and subsequently the latest defect management information is obtained by searching a plurality of defect management areas for a currently active defect management area in which the latest defect management information is recorded. If there is no unused defect management area in which defect management information can be alternatively recorded in lieu of the currently active defect management area, recording operation is limited.

    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.
