摘要： An information recording apparatus includes a writing system for writing the datasets to the recording medium, so that each of the datasets can be identified from a certain number indicating an order that each of the datasets was sequentially written to the recording medium, and from the number of writing operations (WP) carried out for a dataset of the certain number, the writing system writing a first dataset; the writing system being configured for substantially appending a second dataset onto the first dataset, the second dataset having the same certain number as the first dataset, and for setting a value obtained by incrementing the WP of the first dataset as the WP of the second dataset. A writing control system controls, in the case where an error occurs at the time of the appending, the appending on the first dataset, in a position shifted forward by a predetermined distance from the position of the first dataset on the recording medium, by setting the value obtained by incrementing the WP of the first dataset as the WP for the second dataset, wherein the predetermined distance is a distance with which error correction of the first dataset is avoided by appending the second dataset onto the first dataset so that the second dataset overwrites a part of the first dataset.

摘要： There is provided a tape recording apparatus system capable of improving writing performance and maintaining tape recording density, for a multiple data writing request accompanied by a lot of synchronization requests from a host.
The system is a tape storage system including two or more tape drives each of which has a tape mounted thereon and is provided with a buffer divided in fixed-length segments, and connected to a host that sends multiple data and a synchronization request at a predetermined timing to these tape drives. This tape recording system is provided with: a tape drive connected to the host, receiving the multiple data sent from the host, and, when the segment of the buffer is accumulated and filled with data, writing the accumulated data onto a tape; and another tape drive connected to the tape drive, receiving the multiple data sent from the host via the tape drive, and dumping a predetermined number of data accumulated in the segments onto a tape at a timing of receiving the synchronization request.

摘要： Data of a target capacity calculated by a nominal capacity of a tape medium minus a data capacity lost due to execution of backhitchless writing is written to the tape medium. In a tape drive, a command processing unit 41 receives a synchronization command, and a buffer management unit passes data in a buffer to a channel input-output unit. Upon completion of writing the data to the tape, a backhitch determination unit determines whether a mode information storage unit stores information indicating that a high data rate mode is on, whether data of a target capacity can be written to the tape, and whether the written data can be read at a target read data rate. An operation signal output unit issues a command to execute backhitch in case these conditions are not satisfied.

摘要： A tape drive, tape drive recording system, and method are provided for improving tape speed selection during data transfer. The tape drive includes a buffer, a tape for recording the data to be temporarily stored in the buffer, and a read head. The tape drive further includes a reading controller that initially sets a tape speed such that a drive transfer rate matches a host transfer rate as closely as possible and that drives the tape at the tape speed. To address backhitching caused by one or more host transfer halts, the reading controller subsequently adjusts the tape speed such that the drive transfer rate is lower than the host transfer rate by recalculating the host transfer rate in consideration of the host transfer and the host transfer halt and setting the tape speed such that the drive transfer rate matches the recalculated host transfer rate as closely as possible.

摘要： A tape drive capable of switching the transport speed of a tape medium among multilevel speeds calculates a data transfer rate from/to a host device, and selects an adjustment mode of the transport speed of the tape medium from a constant speed mode and a speed switch mode according to the calculated data transfer rate. The tape drive in the speed switch mode, pauses a data write or read operation to switch the transport speed of the tape medium while data is written at a first transport speed and when an available capacity of a buffer memory reaches a data volume to be received from the host device during switching of the transport speed and is read out at the first transport speed and when a data volume of a buffer memory reaches a data volume to be transmitted to the host device during switching of the transport speed.

摘要： Provided is a storage mechanism that readably migrates a content of data from one recording medium to another over generations in a readable manner and provides the contents of the records from a current recording medium. A read/write controller comprises a mechanism for preparing an archive recording medium of a first generation having a plurality of records recorded therein and a mechanism for migrating the records from the recording medium of the first generation to a recording medium of the next generation (the third generation subsequent to the first generation) and further to recording media of following generations one by one. The migration mechanism generates migration information including a mapping table between record numbers of the first generation and a current generation and holds the migration information as data in the recording medium of the current generation.
