Abstract
A tape apparatus includes a controller and a plurality of tape drives. The controller controls reading from and writing onto magnetic tapes by the use of the plurality of tape drives. Furthermore, when the controller receives a data write request, the controller writes received data both onto one of main data magnetic tapes and onto an auxiliary data magnetic tape. In addition, each time the controller receives a data write request, the controller writes received data onto a corresponding main data magnetic tape and adds the received data onto a common auxiliary data magnetic tape.
