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.

摘要： Special fields for error recovery are provided in data set information tables of data sets written with synchronized transactions. If a transaction only partially fills a data set, that data set is rewritten in a succeeding data set, appending the next transaction. A moving access point in the table identifies the appended transaction, allowing the rewritten transaction to be skipped during read recovery. The table provides recovery trails by providing a thread to tie the data sets together, the status of the data set, and pointers, such as identifying the wrap of the immediately succeeding data set.

摘要： Backspacing over data to overwrite the data as recorded on magnetic tape is provided logically, rather than by causing a magnetic tape to drive to backhitch. The data is written to the magnetic tape as it was before it was logically changed in order to insure that the data is preserved on tape. Recovery of the data is from a succeeding data set which logically invalidates the original data by a superseding identifier. Control logic arranges data transactions for writing to magnetic tape as data sets; and, in response to backspace and overwrite commands, or when transactions are accumulated into a succeeding data set, rewrites the original transaction adjusted in accordance with the commands as a superseding data set downstream from the original transaction, logically invalidating the original transaction by setting a superseding identifier in the superseding data set(s).

摘要： A write/read control method for recording at least one datum on a magnetic tape within a predetermined distance is provided. The method includes sequentially accumulating a plurality of blocks of data of variable length in a buffer divided into fixed length segments and writing the contents of each segment to the tape. If the segment contains at least one block of data, the data is written to the tape as a dataset and if the segment does not contain any data, then a null dataset is written to the tape within the predetermined distance. The predetermined distance may vary depending upon the format of a tape drive embodying the method. In response to a request to read a block of data, reading at least one dataset that includes the requested block of data from the tape to segments in the buffer, and reading the requested block of data for invalidating data transfer of a null dataset in the segment. By invalidating the transfer of a null dataset, blocks of data separated by the null dataset can be reconstructed.

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。
