Hi, Richard,
That is a totally different problem. I don't recall ever seeing that in
a DAT tape, but I have seen it in reels and cassettes.
In the cases I've seen, the rip starts because there is both adhesion
and damage at that point.
In one case, it was an acetate 1/4-inch tape that had fallen behind a
Vermont wood stove--for a winter or two--and there was some edge melting
(and bonding) of the tape. After a good deal of work, the client and I
decided to abandon the recovery.
In perhaps several other cases with cassette tapes, it appeared that
some adhesive-like material (highly sweetened coffee, perhaps?) had
spilled into the shell. I suggested unspooling the tape and washing it
as Dr. Bradshaw and his team did with the Challenger tape which had
magnesium salts deposited on it by the salt water corrosion of the
magnesium tape reels. I proposed a reasonable price (from my
perspective) to undertake this radical treatment, but the client declined.
So, if you can identify if this ripping is caused by adhesion and then
identify a means of removing the adhesion, it might play.
Cheers,
Richard
