摘要： When RAID is constructed by using optical disks of the same lot, there is a problem in that the reproduction error probability of the RAID may have local increases over the reproduction error probability within the optical disks. According to the present invention, among a plurality of optical disks constituting an optical disk array, the smallest logical sector number is assigned to mutually different physical sector numbers. As a result, data in the same stripe is allowed to be recorded to sectors at mutually different physical sector numbers of the plurality of optical disks, so that the probability of occurrence of read errors due to interferences of adjacent guide grooves and/or insufficient formation of guide grooves can be leveled out, and the maximum probability of read errors can be kept small.

摘要： According to one embodiment, an information recording apparatus includes a divider (103), a generator (103), and a recorder (102). The divider is configured to divide recording data into a plurality of recording data blocks for each predetermined recording unit. The generator is configured to set, as a first block set, n recording data blocks recorded in corresponding areas in file system management areas of n, first to nth (n: integer, n ≥ 2) storages, and generate first parity data from the n recording data blocks forming the first block set. The recorder is configured to record the n recording data blocks forming the first block set and the first parity data.

摘要： A method of controlling an ODD archive system comprising three or more ODDs is provided comprising storing information on a parity drive in a memory, and setting a parity drive in which parity data is to be recorded based on the information when data recording is requested in a RAID 3 or 4 manner. The information on the parity drive may include a cumulative value of number of times by which each ODD has been set as the parity drive up to now. Or the information on the parity drive may be managed for each of one or more magazine having optical discs the number of which is equal to or less than the number of ODDs included in the archive system.

摘要： In particular, the aim of the invention is to improve the reliability of data storage in a hard disk comprising a plurality of platters, each platter comprising at least one data storage surface. After obtaining (500) a plurality of data blocks, each block needing to be or being stored in the hard disk, at least one redundancy data block is calculated (505) on the basis of each block of said plurality of data blocks, the number of redundancy data blocks added to the number of blocks of said plurality of data blocks being less than or equal to the number of platter surfaces of the hard disk that can store data. Said at least one redundancy data block is then written (510) on a platter surface of the hard disk that is different to the surfaces used to store each block of said plurality of data blocks.
