摘要： An apparatus according to the present invention is designed to perform formatting processing on an information storage medium. The storage medium has a data storage area including a user data area and a spare area. The user data area is provided to write user data on, while the spare area includes a replacement block to be used as a replacement for a block that has been detected as a defective block. The replacement block stores instruction information that instructs to read data from the defective block when data is read from the replacement block. The apparatus includes a control section for controlling the formatting processing. In performing the formatting processing, the control section updates information stored in the replacement block such that when data is read from the replacement block, the data is not read from the defective block.

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）。
