disk controller

   The electronic circuitry that controls and manages the operation of floppy disks and hard disks. A single disk controller may manage more than one hard disk. Many disk controllers also manage floppy disks and compatible tape drives. In the Macintosh, the disk controller is built into the system. In the PC, the disk controller may be a printed circuit board inserted into the expansion bus, or it may be part of the hard disk drive itself.
