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, Chuck
