摘要： In a controller of a tape drive, when a command processing unit receives a Write FM0 command, a channel input/output unit writes the data in the buffer and a speculative FM onto the tape, and a CM input/output unit records speculative FM presence information in a cartridge memory. When the command processing unit receives Write FM1 command next, the CM input/output unit erases the speculative FM presence information from the cartridge memory. When the command processing unit receives a command other than Write FM1 command next, the channel input/output unit overwrites a speculative FM.
摘要翻译：在磁带驱动器的控制器中，当命令处理单元接收到写FM0命令时，通道输入/输出单元将数据写入缓冲器和推测FM到磁带上，并且CM输入/输出单元记录推测FM存在盒式存储器中的信息。当命令处理单元接收到写FM1命令时，CM输入/输出单元从存储器存储器中擦除推测FM存在信息。当命令处理单元接收到除了FM1命令以外的命令时，通道输入/输出单元将覆盖推测FM。

摘要： A plurality of tape drives writes a plurality of indicators corresponding to a plurality of data units on a tape, wherein an indicator indicates which tape drive of the plurality of tape drives has written a corresponding data unit on the tape. Each of the plurality of tape drives generates an extent of read errors, in response to reading the plurality of data units written on the tape. The extent of read errors generated by each of the plurality of tape drives are aggregated at a computational device coupled to the plurality of tape drives. A determination is made at the computational device of a defective tape drive of the plurality of tape drives from the aggregated extent of read errors.

摘要： A method to write information to a tape storage medium by disposing a tape storage medium in a tape drive apparatus comprising a write head. The method moves the tape storage medium in a first direction, writes data from a buffer to the tape storage medium, and thereby empties the buffer while the tape storage medium is moving in the first direction. The method determines, while the tape storage medium is moving in the first direction, whether to enable a backhitchless write wherein the tape storage medium is not stopped and moved in a second and opposition direction, prior to writing new data to the tape storage medium. By not stopping the movement of the tape storage medium, and by not moving the tape storage medium in a reverse direction to reposition the write head, the method eliminates the time overhead required to stop the tape and reposition the tape head. Applicants' method achieves this time efficiency without adverse impact to the nominal storage capacity of the tape information medium.
摘要翻译：一种通过将带存储介质配置在包括写入头的带驱动装置中来将信息写入磁带存储介质的方法。该方法使磁带存储介质沿第一方向移动，将数据从缓冲器写入磁带存储介质，从而在磁带存储介质沿第一方向移动时清空缓冲器。该方法在磁带存储介质在第一方向上移动时，确定在将新数据写入磁带存储介质之前是否启用磁带存储介质在第二和相对方向上不停止和移动的无间隙写入。通过不停止磁带存储介质的移动，并且通过不使磁带存储介质沿相反方向移动以重新定位写入头，该方法消除了停止磁带所需的时间开销并重新定位磁带头。申请人的方法实现了这种时间效率，而不会对磁带信息介质的标称存储容量产生不利影响。

摘要： A method for recording data freshness degrees by a tape drive is disclosed. During the recording of a set of data and a data freshness degree associated with the set of data a tape recording medium, a determination is made as to whether or not a fault occurs during the recording. In response to a determination that a fault occurs during the recording, a data freshness degree of data within a faulty portion on the tape recording medium is obtained. The data freshness degree of the set of data is then immediately recorded before the faulty portion on the tape recording medium. The data freshness degree is higher than the data freshness degree of data within the faulty portion.

摘要： Provided are a method, system, removable storage cartridge, and article of manufacture for validating an encryption key file on a removable storage media. Copies of an encryption key file are written to multiple locations on a removable storage media, wherein data is encrypted and decrypted using an encryption key included in the encryption key file. A validation operation is performed on the copy of the encryption key file at one of the key locations, wherein the key locations comprise the locations on the removable storage media to which the encryption key files were written. In response to the copy of the encryption key file not validating, a command is sent to cause the data and valid copies of the encryption key file to be rewritten to a new storage media.
