When I ran the tape library at calma we had one of those, only mine
would run the tape over a razor blade to scrape off junk, and would
record and playback an analog signal looking for dropouts. It had
counters
that recorded tape faults and would print out a strip of
addingmachinepaper with a report on the reel.
More than a certain number of dropouts, we scavenge the write ring and
reel cover and toss the tape.

Does anyone know anything about 1/2" tape cleaners?
I remember (I think) seeing a device in the tape library of the giant
insurance company I once worked for.
This device, if I remember correctly looked like an audio open reel
tape deck
but would take a 1/2" (9-track style) tape reel on one side and had a
take-up
reel on the other.
If I remember correctly the tape passed over a "spinning wheel" which
had slots in it. I think this wheel would "clean" the tape.
It's all a bit hazy now, but I think this device was used to clean and
re-tention 9-track 1/2" tapes. (the # of tracks does not matter, but I
say
that to give the proper context).
Anyone know of these, have one, know of one, or if they work and are
safe?
I have some (well, many) 9-track tapes which were stored in a very poor
(read humid) environment. The look like they have mildew on them. I'd
like to try cleaning and re-tensioning one and, after baking, see if it
will read.
Seems like one of these devices would come in handy.
Any experience?
