minimum seek time

from The Free On-line Dictionary of Computing (8 July 2008)

minimum seek time

   <storage> (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.
