track
     
         The part of a {disk} which passes under one
        read/write head while the head is stationary.  The number of
        tracks on a disk surface therefore corresponds to the number
        of different radial positions of the head(s).  The collection
        of all tracks on all surfaces at a given radial position is
        known a {cylinder} and each track is divided into {sectors}.
