Abstract
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.
