摘要： When a WORM cartridge is formatted for Tape File System (LTFS) in advance, such as prior to shipment, Linear Tape File System Library Edition (LTFS LE) is expanded by software to reduce consumption of the index partition and to support elimination of the appending of unnecessary data. More specifically, instead of recording metadata in the index partition during normal unmounting, the metadata is recorded in separate local storage such as on hard disk drive (HDD), and the index partition is updated only when the cartridge is ejected from the library. In this way, the present invention is able to significantly reduce the frequency of index partition updates. Because an update occurs only when the user intentionally ejects a cartridge, overflow of the index partition before overflow of the data partition can be prevented.

摘要： In a controller of a tape drive, when an error recovery section cannot recover an error detected by an error detecting section, an error-report generation section generates an error report, an error-information acquisition section acquires error information of the tape drive and a cartridge loaded in the tape drive, an error-information exchange section acquires pieces of error information of other tape drives and cartridges loaded in these other tape drives, an error-factor judging section judges whether the error is attributable to the tape drive or the cartridge based on these pieces of error information, an error-report update section updates the error report in accordance with the result of this judgment, and an error-report output section outputs the error report thus updated to a host.

摘要翻译： 在磁带驱动器的控制器中，当错误恢复部分不能恢复由错误检测部分检测到的错误时，错误报告生成部分生成错误报告，错误信息获取部分获取磁带驱动器的错误信息和 装载在磁带驱动器中的磁带盒，错误信息交换部分获取装载在这些其他磁带驱动器中的其它磁带驱动器和磁带盒的错误信息，错误因素判断部分判断磁带驱动器或磁带盒是否归因于错误 基于这些错误信息，错误报告更新部根据该判断结果来更新错误报告，并且错误报告输出部将所更新的错误报告输出到主机。

摘要翻译： 当WORM墨盒预先格式化为磁带文件系统（LTFS）时，例如在出货之前，线性磁带文件系统库版本（LTFS LE）由软件扩展，以减少索引分区的消耗，并支持删除附加 的不必要的数据。 更具体地，在正常卸载期间，不是在索引分区中记录元数据，而是将元数据记录在诸如硬盘驱动器（HDD）之类的单独的本地存储器中，并且仅当盒从库中弹出时才更新索引分区。 以这种方式，本发明能够显着降低索引分区更新的频率。 因为只有当用户有意地弹出盒式磁带时才会发生更新，所以可以防止索引分区在数据分区溢出之前溢出。
