  From  The  Free  On-line  Dictionary  of  Computing  (13  Mar  01)  [foldoc]: 
 
  cylinder 
 
    The  set  of  {tracks}  on  a  multi-headed  {disk}  that 
  may  be  accessed  without  head  movement.  That  is  the 
  collection  of  disk  tracks  which  are  the  same  distance  from  the 
  spindle  about  which  the  disks  rotate.  Each  such  group  forms 
  the  shape  of  a  cylinder.  Placing  data  that  are  likely  to  be 
  accessed  together  in  cylinders  reduces  the  access 
  significantly  as  head  movement  ({seeking})  is  slow  compared  to 
  disk  rotation  and  switching  between  heads.
