  constant angular velocity
  
     <storage> (CAV) A disk driving scheme in which the angular velocity
      of the disk is kept constant.  This means that the
     linear velocity of the disk be larger when the reading or
     writing the outer tracks.  The disadvantage of this technique
     is that the read/write speed varies from track to track.
     However, as mechanical stability puts an upper limit on the
     angular velocity (and not the linear velocity) this allows the
     full potential of the drive is used.
