[QuadList] Scotch 400

[Shai Drori]

Hi All
I am digitizing an archive now that has among other media 28 reels of 
scotch 400. When I checked them visually for sap or SSS or other 
problems they actually looked fine. Could use a cleaning before playing 
but they actually looked good. Is that possible? I was always under the 
impression that all these are disasters.
With this in mind I would like to know what you think about the follow 
work flow for preparing them for transfer.
1. clean and vacuum off dust.
2. remove flanges and clean them.
3. remove foam from top flange, even if it's in good shape and clean 
flange from residue.
4. screw flanges back into place.
5. run tapes forward and back while cleaning tape surface from dirt and 
loose particles.

In this batch there are also 3 tapes in bad condition with heavy deposit 
of fungus and mold on tape where the windows are. How should I go about 
getting these clean?

And last, there are two memorex tapes, when labeled Chroma 90. What do 
we know about them? Any thing to look out for?
Cheers
Shai
