I was trying to archive a bunch of 8 inch floppy disks. Everything was well
until I tried an Inmac brand disk. It had severe sticky shed problems.
Since it was a non-important disk it wasn't that bad. Baking might solve
the problem so before continuing with the rest of the Inmac branded disks
with more valuable content I searched internet for knowhow on baking.
Then I found this article
https://www.questia.com/library/journal/1G1-359998950/the-new-non-baking-cu…
on a cure for the sticky shed without baking the tape.
I haven't read the article in ARSC since I am not a member. But maybe
someone knows what this is about?

Much ado, IMOHO, about little.
There's an associated patent:
https://patentimages.storage.googleapis.com/pdfs/US6797072.pdf
that relates to this. Essentially, it's a system for cleaning the front
and back of a tape. It was greeted with some skepticism on the ARSOList
mailing list and I can find nothing much after that.
Try this for your Inmac disk (I used to buy cables and such from
them--Inmac blue):
Bake the disk first.
Get yourself some cyclomethicone (D5 lubricant) and coat both the front
and back of the disk by swabbing it on the surface, then rotating the
disk, then repeating until the entire surface is coated, then read the
disk immediately. D5 is somewhat volatile and will eventually evaporate
completely. I've used this method for very severely compromised disks
and tapes where the binder has actually bled through to the oxide
surface with great success. In the case of tapes, I mount the tape on
my cleaning machine and use a thick felt strip to wipe the stuff on.
You can use any excess D5 to untangle your hair (used in a lot of
shampoos and horse grooming stuff). Utterly inert chemically.

OK. I followed this very good advice and it was a 100% success! The disk
which when I previously tried to read it sounded very bad and when I
stopped the reading there was a circular track on the disk where you could
see through it - now it read perfectly - not a lost sector!
I baked it for approximately one hour before reading. It seems to have been
enough.

I guess that my daughters will have more use for it than I, but I doubt
that they find a bottle marked "Deoxit D5" very appealing to use in their
hair.
Once again thanks for this piece of very good advice!

Deoxit D5? Is that cyclomethicone?
Another place other than shampoos and lotions that you'll find the stuff
is in "Show Sheen" horse mane and tail detangler.
I suspect that other human hair care brands, such as Pantene, also have
some of the stuff.

Oops. It was what came up when I searched for "D5
lubricant". I tried
to check the contents but it looked very secret.
Maybe "Deoxit D5" is the wrong stuff. Anyway the good thing is that
the disk read very well.
I think you were just plain lucky. According to the D5L MSDS at:
http://store.caig.com/core/media/media.nl?id=922&c=ACCT113328&h=f0f…
D5L is mostly petroleum maphtha with 5% "secret sauce"
(That's one of the reasons that I give the chemical name also :) The
next time it could mean a fudge brownie mix).

Mattis et al,
I also ran across this info, here are links to the article and related
material:
Paper:
https://www.dropbox.com/s/edgts703ycr1j7l/The_new__non-baking__cure_for_.PD…
Correction:
https://www.dropbox.com/s/57vgollh4b8im5j/Correction___clarification.PDF?dl…
Patent: https://www.dropbox.com/s/ytkai85qiqny9oj/US6797072.pdf?dl=0
Appears that the inventor has a commercial entity to process tapes with
sticky shed syndrome:
https://www.dropbox.com/s/i22eh95id3bus22/Rezerex%20Process.pdf?dl=0
I have no connection with this person, just found this info researching
sticky tapes. Sounds like there has been an independent assessment done of
the technique WRT to audio tapes. Would be interesting to know if if his
technique has been applied to data tapes.
One thing I don't understand is does removing the backing from the tape
(which seems to be the heart of this technique) degrade the mechanical
integrity of the tape? I'm not a chemist or mechanical engineer so have no
idea.

If you're really interested in tape restoration, Richard Hess runs a
service professionally and has gobs of information.
http://www.richardhess.com/tape/
Yes, I know he specializes in audio (analog) tape, but as Bob Pease used
to say, "at some level, everything is analog".

tape is tape all thats different is is the signal thats put on it.

Nonsense-substrate, binder, magnetic characteristics vary widely between
analog/audio and digital/computer tapes. Try taking some VHS tape and
using it in your 9-track open-reel drive.
Or how about recording audio on some old Univac Uniservo metal tape?
