Abstract

PURPOSE:To reduce the redundancy of a disk device to be connected by sending an N-bit reading information signal obtained by interpolating a bit information signal corresponding to a magnetic disk device generating a fault to a central processing unit (CPU). CONSTITUTION:A parity generating circuit 18 forms a parity signal 102 from an inputted information signal 101 and inputs the signal 102 to a reading/writing (R/W) circuit 17-P. A control circuit 17 informs the device number of a disk device 7 generating a fault to an inversion instructing register 16 and the R/W circuit 17 sends a bit information signal read out from a disk device 7 to an inversion circuit 19 and a parity check circuit 20. At the time of inputting a parity error signal 106, the circuit 19 reads out the disk number of the disk device generating the fault from the register 16, interpolates the corresponding bit information signal and sends a correct 8-bit reading information signal to a host 2 through an interface circuit 14. Consequently, the system can be prevented from generating system down when a fault is generated in a magnetic disk device.
