One tape manual I had about 5 years ago warned that we use only
dehydrated alcohl, meaning alcohl that doesn't contain water.
It turns out many "alcohl" sold contains water and
we have to ask for dehydrated alcohl.
The reasoning seems to be that the water in the diluted alcohl
can possibly reacts with the iron oxide particles and can make a
somewhat larger particle that can probably either tear the tape itself
during the drive's working or tear the head quicker or something.
(Someone with better knowledge can explain this.)
The manual DID suggest that we clean the tape head, etc..
after certain hours of use. Mine recommended one after 8 hours of
usage or something, but this, of course, depends on the driver
characteristics.
So now I have a bottle of dehydrated alcohl (it was ethanole or
something) in a secure corner of the house.
Beware. It is imflammable.
BTW, I will try to test the new .36 kernel if the
problem we mentioned about strange bug with Nakamich
CD changer has been solved or not...
Maybe the SMP fix might have some bearing on the outcome of the test.
Just a hunch.
