TAPE STORAGE SYSTEM INCLUDING A PLURALITY OF TAPE RECORDING DEVICES

摘要

Disclosed is a tape recording device system wherein tape recording density can be maintained and writing performance can be improved in respect of write requests for a plurality of data items accompanying a large number of synchronisation requests from a host. This system is a tape storage system including two or more tape drives in which respective tapes are mounted and having buffers divided into segments of fixed length; the tape storage system is connected with a host that sends synchronisation requests at a prescribed timing and a plurality of data items to these tape drives. This tape recording system is provided with: a tape drive that receives a plurality of data items delivered from the host to which it is connected and that, when a buffer segment is filled with accumulated data, writes this accumulated data onto a tape; and another tape drive which is connected with the first-mentioned tape drive and receives a plurality of data items delivered from the host through this first-mentioned tape drive, and exports to a tape a prescribed number of data items accumulated in a segment at the timing with which a synchronisation request is received.
