"It was considered less severe because tails out print through came after a
loud section, and heads out caused print through before the loud section."

Also, tails out gave a post-echo which was/is far more acceptable than
pre-echo.

Well, If you want to talk about open reel tapes and analog masters...

The other important reason for storing tails out was "Print Through" It was
considered less severe because tails out print through came after a loud
section, and heads out caused print through before the loud section.

The following is quoted from an AES Technical Bulletin A011194 (link follows
quote):

"There are a few steps you can take to minimize print-through. The most
common is to store your tape tails out.
Normally, the outer layers of tape from the printing signal will receive
more print-through than the inner layers, since the signal must reach the
top of the oxide coating to be noticeable. To reach the top surface of an
outer layer of tape, that signal's magnetic field needs only to pass through
the base material. To reach the top surface of an inner layer of tape, it
must pass through both the base material and the oxide. So by storing tape
tails out, the strongest print-through will be postprint. This is less
offensive than preprint, because post-print will be masked by the recorded
signal on playback."

I remember in the Army, we were always supposed to send tapes on to the next
station "tails-out", whether they were reels or cassettes. The logic was
explained that tow factors were involved: 1- the receiving station would be
able to properly tension the tapes after shipping, 2- if a tape were to
have a mechanical issue, it would be in the tail and easily spliced, versus
making the head shorter.

Me, I always tried to store tapes rewound. Even had a betamax rewinder to
save wear on the decks. Had to watch it with old Red shell Scotch tapes, as
it would snap the leader rather than stop.

Of course, you mileage may vary.

Is this really true? I've never archived much on tape, but I'm not sure I
can see any reason why it would be better to store the tape in a rewound
position, other than to avoid confusion for the next person to use the
tape...
