Abstract
A disk controller for a plurality of disk drives is disclosed. This controller includes a plurality of first memory units, the number of which is equal to the number of the disk drives and each of which stores a group number representative of a kind of the associated disk drives, and further includes a plurality of sets of second memory units, the number of which is equal to the number of the kinds of the disk drives and each of which stores control parameters used for controlling the associated kind of the disk drives. One of the first memory units is accessed in response to a disk drive selecting signal and one of the sets of second memory units is selected in response to the group number read out from the accessed first memory units. The controlled parameters stored in the selected set of second memory units are thereby read out to control the disk drive.
