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： [Object]
To provide a technique for continuing to read data rapidly and appropriately when a read error occurs.
[Solution]
A tape reader comprises a reading section for reading data in data units from a tape medium, a reading control section for controlling the data reading section to read data in accordance with a command from a host computer, and on condition that an error occurs in reading the data unit, to skip an error data unit where the error occurs and read the next readable data unit immediately after the error data unit, a computation section for computing the number of records and the number of boundary marks included in the data unit where the error is detected from the information on the records and boundary marks indicating the boundary of record block included in the data unit preceding to the error data unit and the information on the records and boundary marks included in the data unit next to the error data unit, and a communication section for sending the number information on the computed number of records and the computed number of boundary marks to the host computer.
