not really from Steve, 
	but from Mike Andrews on his tty and with his consent

There are two ways to store tape: "tails-in" and "tails-out". A tape is   
"tails-in" if it is rewound after being played or recorded, and              
"tails-out" if it is left on the takeup reel after being played or          
recorded. Note that a "tails-out" tape must be rewound to be played. 
   The reason for storing tapes "tails-out" is to put them on the reel
at a constant tension, rather than at the variable tension imposed by     
rewind motors at full-tilt-boogie. It seems to me that print-thru will
be more apparent in those layers that are at higher tension, and 
(from my experience producing an early-music radio show for 6 years)
that rewind on all the machines I've used is at much higher tension
overall than that imposed by the takeup-mode motor.
   Mind you, I have no theoretical basis for my statements, and I hope     
you won't flame Steve for them; I'm the one who typed this missive. How-
ever, it does seem that it works that way in practice. Perhaps that's
why most recording studios, networks, stations, etc. store their tapes
"tails-out".
   I am obliged to you all for your kind attention.
