minimum seek time
     
         (Or track-to-track seek time) The time it takes to
        move the head of a {disk drive} from one {track} to the next.
        The minimum seek time gives a good measure of the speed of the
        drive in a single-user/single-process environment where
        successive read/write request are largely correlated and thus
        if correlated data is stored in nearby cylinders most seeks
        are from one cylinder to the next.
