    • A storage device according to the present invention constructs a RAID structure using a plurality of detachable recording mediums. When a first drive device fails to reproduce data from a recording medium, a transport device transports the recording medium to a second drive device different from the first drive device which failed to reproduce the data, and the second drive device attempts to reproduce the data from the recording medium, the data reproduction from which failed. Owing to this, even when faults of a number exceeding the number of faults correctable by the RAID structure occur, the probability that the data is recovered can be improved.
    • 根据本发明的存储装置使用多个可拆卸记录介质构造RAID结构。 当第一驱动设备不能从记录介质再现数据时,传送设备将记录介质传送到与第一驱动设备不同的第二驱动设备,该驱动设备不能再现数据,并且第二驱动设备尝试从 记录介质,数据复制失败。 因此,即使出现超过由RAID结构校正的故障数量的故障,可以提高数据恢复的可能性。

    • 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).
    • 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)。

    • An information recording apparatus is provided with a recording controller for recording data on an information recording medium, a verification controller for verifying whether or not the recorded data can be correctly reproduced, a continuous recording controller for providing a gap region of a specified interval between a verification region and a recording region and successively performing a verify processing and a record processing with rotation waiting in between, an error region discriminator for discriminating an error region in the event of an error in the process of performing the verify processing and the record processing, and an error processor for performing an error processing according to the error region. The error processor performs an error processing different from the one performed when an error occurred in either one of the verification region and the recording region if an error is discriminated to have occurred in the gap region. By this construction, a recording time is shortened and it is prevented that data cannot be recorded on the information recording medium.
    • 信息记录装置设置有用于在信息记录介质上记录数据的记录控制器,用于验证记录数据是否可以被正确再现的验证控制器,用于提供记录数据之间的间隔区域的连续记录控制器 验证区域和记录区域,并且在循环等待中继续执行验证处理和记录处理,用于在执行验证处理的处理和记录处理的过程中识别错误区域的错误区域鉴别器, 以及用于根据误差区域执行错误处理的错误处理器。 错误处理器执行与当在差异区域中出现错误时,在验证区域和记录区域中的任一个中发生错误时执行的错误处理。 通过这种结构,缩短了记录时间,并且防止了数据不能被记录在信息记录介质上。
