Abstract

PURPOSE: To perform copying without lowering the system processing ability, by enabling to execute the processing to the auxiliary memory unit in which the control unit with staging function is normal even during copy operation.
CONSTITUTION: To the cartridge copy instruction from the host CPU 1, the mass storage control unit 2 performs instruction to the cartridge store 3 so that the copied cartridge 5 designated is set to the momory sets 5 and 7 designated, and gives instruction to the control unit 11 with staging function so that two recoreding units 6 and 7 which are the bus transferring data during operation and the recording set control unit 8 are restricted as broken lines. Then, the information of the cartridge 4 is transferred until the data buffer storage 12 is full through the set 6 and the unit 8 for the information in the cartridge 4, and when it is full, the content is transferred to the cartridge 5 through the unit 8 and the set 7. This operation is executed until the content of the cartridge 4 is all copied. During this, the job reception of the real disc 9 having greater access frequency and the execution are parallelly performed and the system processing ability is not lowered
