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： On a recording medium, data is recorded on at least one of a plurality of recording layers by laser light incident on a surface of the recording medium. The plurality of recording layers include a first recording layer, and second through N-th recording layers (N is an integer of 3 or greater) which are sequentially located in a direction from the first recording layer toward the surface on which the laser is incident. The plurality of recording layers each have a first calibration area and a second calibration area located outer to the first calibration area. The first calibration area located in each of the first through N-th recording layers is located at a different radial position from a radial position of the first calibration area in each of the other recording layers; and the second calibration area located in each of the first through N-th recording layers is located at the same radial position as a radial position of the second calibration area in each of the other recording layers.

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）。

摘要： According to the present invention, multiple space bitmaps (SBMs #0 and #1 30) are provided for the user data area of each recording layer. A disc management structure update unit including one of those space bitmaps and a disc definition structure (TDDS 32) and having a size of one block is written on a management information area (TDMA 17). As a result, data including the disc definition structure (TDDS 32) can always be arranged in the first block at the top of the management information area (TDMA 17).

摘要： OPC areas are used for adjusting recording parameters (power and strategy). In an optical disc including two recording layers, the recording power for one recording layer is likely to be influenced by a transmittance variance or the like provided by the recording state of the other recording layer (either already recorded or unrecorded). In addition, recording is performed while changing the power. For these reasons, the OPC areas are located so as not to be at the same radial positions among the recording layers. However, as the number of recording layers is increased, the area size for securing the OPC areas is increased, which may undesirably lead to an increase of the lead-in zone or the lead-out zone (decrease of the user data zone) and a decrease of the OPC area size in each recording layer (decrease of the number of times of usage by the user). According to the present invention, an area for power calibration in which recording is performed while changing the power and so which is significantly influenced by the transmittance balance, is separated from an area for strategy calibration or the like in which recording is performed at a fixed power suitable to the disc and so which is unlikely to be influenced by the transmittance balance. Only power calibration areas are located at different radial positions among different recording layers so as not be influenced by the recording state of the other recording layers, and the strategy calibration areas are located so as to include the same radial position among different recording layers.
摘要翻译： OPC区域用于调整记录参数（功率和策略）。在包括两个记录层的光盘中，一个记录层的记录功率可能受到另一个记录层的记录状态（已记录或未被记录）提供的透射率变化等的影响。另外，在改变电源的同时执行记录。由于这些原因，OPC区域被定位成不在记录层之间处于相同的径向位置。然而，随着记录层的数量的增加，用于固定OPC区域的区域尺寸增加，这可能不期望地导致引入区或导出区的增加（用户数据区的减少）和每个记录层中的OPC区域尺寸的减小（用户使用次数的减少）。根据本发明，用于在改变对透射率平衡的显着影响的功率进行同时进行记录的功率校准区域与用于策略校准等的区域分离，其中以固定的方式执行记录适用于光盘的功率，因此不太可能受透射率平衡的影响。只有功率校准区域位于不同记录层之间的不同径向位置，以便不受其它记录层的记录状态的影响，并且策略校准区域被定位成在不同的记录层之间包括相同的径向位置。
