ABSTRACT:
The electromagnetic noise radiated from a magnetic disk system comprising two or more magnetic disk drives is reduced so as not to exceed a certain level although the electromagnetic noise from each magnetic disk drive is added up. This is achieved by setting a different operation clock frequency for each SCSI-ID so that the electromagnetic noise radiated from each magnetic disk drive has a different frequency band.
