Hi, good folks. I get completely confused by Agfa tapes. I don't see
that many of them here in North America, and they often seem to surprise
me with their nastiness.
Today's tape is a 10.5" reel of 1" 16 Track Agfa PEM469. It was recorded
at the end of January 1988.
On my degrading tapes page, I have listed under SSS as generally
responding to baking this note:
*Agfa PEM 468, PEM 469* (a half-year's worth of batches pre-1990) Note,
there are mixed reviews on these tapes and most of the bad tape was
recalled and transferred at Agfa's expense. See below, however, for
other Agfa issues. Unike Ampex/Quantegy, we do NOT recommend baking Agfa
tapes as a matter of course.
Then, later on the page under the heading:
*Back-coat turning to powder and causing spacing loss* (seems to respond
*Agfa PEM-526* exhibited this odd behaviour. See our article here
A similar condition was reported with
*Agfa PEM-469*, see this article
<http://www.tomshardware.co.uk/forum/page-42797_32_0.html>. Do NOT bake
these tapes. It won't help and may hurt.
Ok, so that is what I think I know about this tape.
The current tape is showing some features of SSS, but what is happening
is a whitish, yellowish waxy substance is coming off on the heads and on
the Pellon. There appears to be some oxide transfer to the back-coat
because the capstan which touches the back has become brown.
I am nervous to bake these tapes. I have a second one and I'd rather not
have to do it in segments. Any suggestions
The link for the PEM-469 has Mike Rivers saying,
"Stand back, let it shed, and clean the tape deck's heads and guides
as often as necessary. Lots of this tape shedded large piles of oxide
even when it was new. There's nothing you can do about it to make it
better, but you've discovered one way to make it worse. Don't bake
the other reels. "
So, that's what I'm doing, but the waxy exudate on the Pellon is new to
me. I've seen other Agfa tapes have dry dust, but this is waxy and
yellow-white, not brown, not black.
Thanks for any suggestions. The transfer is working well. The tape has a
timecode track and I stop when I see it waver ever so slightly and clean.
