摘要： A reproduction type optical disk having same sector structure as that of a recordable optical disk, can reproduce data even if a plurality of sectors are disabled from correction. The disk has data sectors for recording data, parity sectors obtained by a new error correction coding between a plurality of data sectors, wherein the error correction coding between the data sectors is performed by arranging a plurality of data sectors into a matrix and by coding them in directions of row and column doubly to make a product code.

摘要： An optical disk apparatus for an optical disk having two sides for which data can be simultaneously recorded. Each of the two sides includes a spare area for alternative recording. In the optical disk apparatus, a series of data to be recorded is distributed into first data for the first one of the two sides and second data for the second one of the two sides. The apparatus of this invention detects any defective sector into which data cannot be recorded which occurs in either one or both sides during the simultaneous recording. If there is a defective sector in one side, an alternative recording process is performed for alternatively recording data that was to be recorded into the detected defective sector, and data to be recorded into a sector in the other side corresponding to the defective sector, into alternative sectors in the spare areas of the two sides, respectively. Also, defect information relating to the defective sector is recorded into a predetermined area of the optical disk. When the first data and the second data are reproduced, the first and second data are integrated and rearranged, so as to reproduce the series of data.

摘要： In an information recording medium in which storage capacity per recording layer has increased so much that the size of an SBM varies with those of spare areas, there is mutual dependence between a DDS and an SBM and it is difficult to retrieve disc management information as intended. In an information recording medium according to the present invention, if the largest space is allocated to an user data area, the number of blocks to store a space bitmap is Ni (where Ni≧2). But if the smallest space is allocated to the user data area, the number of blocks to use is smaller than Ni. In such an information recording medium, if the number of blocks to store the space bitmap of a recording layer is Mi (where 1≦Mi≦Ni) and if Mi is equal to or greater than two, the space bitmap is divided into the 1st through Mith space bitmaps, each of which has a size that is still equal to or smaller than one block even when combined with a DDS, and each space bitmap is stored in an associated one of Mi blocks in a disc management area.

摘要： If a defective cluster in a spare area is managed with a defect entry, the size of a DFL will increase as the size of the spare area increases with an increase in the number of recording layers stacked in a disc. An information recording medium according to the present invention has pointer information indicating the location of the next available cluster in each spare area, and restricts the direction in which the spare area is used. Also, a defect entry indicating a defective cluster in the spare area is registered with the DFL. Thus, even if the size of the spare area 15 increases, the size of the DFL 21 can be kept relatively small. Furthermore, even after physical reformatting is done, a defective cluster, if any, in the spare area 15 can still be recognized as a defect and the control operation can be performed so that a replacement cluster is not re-allocated to that defective cluster (i.e., the defective cluster is not used).
摘要翻译：如果利用缺陷条目管理备用区中的有缺陷的簇，则随堆叠在盘中的记录层的数量的增加，随着备用区的大小的增加，DFL的大小将增加。根据本发明的信息记录介质具有指示每个备用区域中下一可用簇的位置的指针信息，并且限制使用备用区的方向。另外，用DFL登记表示备用区域中的缺陷簇的缺陷项。因此，即使备用区域15的尺寸增加，DFL 21的尺寸也可以保持相对较小。此外，即使在物理重新格式化之后，备用区域15中的缺陷簇（如果有的话）仍然可以被识别为缺陷，并且可以执行控制操作，使得替换簇不被重新分配给该缺陷簇（即不使用有缺陷的集群）。
