This is in reference to my earlier post about Scotch
777 half-inch
open-reel tapes. I'd reported that I encountered a tape that displayed
binder bleed, such that the tape would stick to the heads and guides.
This was a tape that had been both baked and cleaned.
Coating the tape with a film of cyclomethicone allowed it to be
successfully read.
In the latest batch of tapes, I found another one--it behaves identically.
These appear to be only the blue foil-labeled 777s; the yellow paper
labeled ones are fine.
I estimate the manufacture date to be about 1969-70.
FWIW,
