摘要： A data writing apparatus includes a tape drive, a buffer and non-volatile memory. When a synchronization request is received from a device sending data to be written to a tape, the apparatus is operable to copy data corresponding to the synchronization request from the buffer to the non-volatile memory. The data may be stored in the non-volatile memory until at least the time when the data which it is a copy of is written to the tape from the buffer.

摘要： Method and apparatus for temporarily storing multiple data records in a data processing system which includes a host computer, a cache buffer subsystem, and a magnetic tape drive subsystem. A microprocessor, acting in part as a cache manager, directs the transfer of data into and out of a memory in the cache buffer subsystem by setting up a fill address register, a drain address register, and a start of record address register. Through utilization of a CRC byte to detect errors without correction, and a stop bit to locate the end of a record, values of the registers are compared dependent upon whether there is data being filled or drained to properly manage the temporary storage of data within the memory.

摘要： A system, method and data storage device for encrypting data to provide at-rest data encryption of data in the data storage device. The system includes a compression engine for receiving a host data stream packet and selectively generating a compressed data packet, and an encryption engine in electronic communication with the compression engine for receiving an unencrypted data packet from the compression engine. The unencrypted data packet comprises the compressed data packet when the compression engine generates the compressed data packet. The unencrypted data packet comprises the host data packet when the compression engine does not generate the compressed data packet. The encryption engine generates an encrypted data packet having an encrypted component corresponding to the unencrypted data packet and a set of meta data indicative of one or more characteristic of the encrypted data packet.

摘要： The system for gap positioning optimization in a tape drive takes advantage of the presence of a pair of read heads, located one on either side of the write head, to precisely determine the boundary between the inter-block gap and the data blocks adjoining the inter-block gap. In particular, the servo mechanisms in the tape drive note the location of the boundary between the present data block and the inter-block gap formed a the end of the present data block. When the tape is repositioned between data read/write operations, this servo information is used to identify this boundary to initiate the subsequently received data read/write operation. A predetermined amount of inter-block gap is provided at the end of the data block to ensure that subsequently received data is not written on top of the present data block or the overwriting of the next data record begins at the beginning of the data block. The system for gap positioning optimization in a tape drive activates the upstream read head during the tape acceleration process to sense the location of this boundary. The upstream read head senses the presence of a region devoid of data, indicating the inter-block gap, thereby confirming the location of the boundary with more precision than the servo data indication, and positively verifying before the write operation that the selected block is the one desired.
摘要翻译：磁带驱动器中用于间隙定位优化的系统利用位于写入头的任一侧的一对读取头的存在来精确地确定块间间隙与邻接间隔块之间的数据块之间的边界块间隙特别地，磁带驱动器中的伺服机构注意到当前数据块与块间间隙的边界的位置，形成了当前数据块的结尾。当磁带在数据读/写操作之间重新定位时，该伺服信息用于识别该边界以启动随后接收的数据读/写操作。在数据块的末端提供预定量的块间间隔，以确保随后接收到的数据不被写入到当前数据块的顶部，或者在数据块的开始处开始覆盖下一个数据记录。磁带驱动器中的间隙定位优化系统在磁带加速过程期间激活上游读取头以感测该边界的位置。上游读取头检测到没有数据的区域的存在，指示块间间隙，从而以比伺服数据指示更精确的方式确认边界的位置，并且在写入操作之前积极地验证所选择的块是一个需要。
