hard disk
     
         in contrast to floppy disk.  one or more rigid
        magnetic disks rotating about a central axle with associated
        read/write heads and electronics, used to store data.  most
        hard disks are permanently connected to the drive fixed
        disks though there are also removable disks.
     
        high speed disks have an access time of 28 milliseconds or
        less, and low-speed disks run 65 milliseconds or more.  the
        higher speed disks also transfer their data faster than the
        slower speed units.
     
        each surface of each disk is divided into a number of evenly
        spaced concentric circular tracks.  the set of all tracks at
        a given radius on all surfaces the tracks which can be
        accessed without moving the heads are known as a cylinder.
        each track is divided into sectors.
     
        disk drives are commonly characterised by the kind of
        interface used to connect to the computer, e.g. ata, ide,
        scsi.
