color:black'>If I am thinking of the same thing you are describing, there were
two incidents I can recall from the era of the 70s and 80s. I believe it
mostly affected 3M tape. The tape would precipitate a white powdery
residue that would stick to guides and fixed heads on the machines during play
and then on rewind, it would scratch the tape. At first there was a
considerable reluctance to admit there was a problem, but then after a time,,
3M had a program to swap out reels that had the issue. It's been a while but I
think this affected 400 series tapes, maybe 420? I am sure not every reel
got returned, so there is probably still some of it out there. I don't
believe there was ever any definitive explanation of what had happened,
evidently some change in a manufacturing process that had to be undone . .. <o:p></o:p></span></p>
