Re: [Avid-L2] Somewhat OT: Is it better to store (digibeta) tapes in rewound ...

Print through:


Funny... my audio teacher at SD City College actually said that when Led Zeplin recorded "Whole lotta Love"  the echo-ey part where Plant sings...

"Way down inside... woman... you need...it"

was due to the magnetic tape media bleeding into the tape below it.

It may have just been an urban myth, but it affected my way of thinking about archiving.

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...
