Abstract

PURPOSE:To raise the efficiency of a system, by executing data copy processing through a buffer, and constituting so that both a staging disk controller and a magnetic disk device are not used directly for the data copy processing. CONSTITUTION:A data recording control mechanism 4 reads out recording data on an original magnetic tape of the first data cartridge, at a data stripe each, by a reading-out circuit 16 in accordance with a data copying instruction, and writes it at a data stripe each on the magnetic tape to be copied of the second data cartridge through a buffer 21 by a writing circuit 15. In case of this write control, control of a format is executed by a controlling circuit 17. Also, such control as writes a data read out from the first data cartridge in the buffer 21, or reads out data written in the buffer 21 is executed by a control part in accordance with the instruction of the controlling circuit 17.
