I would not clean any pack that had a lubricated disk
surface.
Perhaps we could find out exactly what IBM used, then used a suitable
(or exact) replacement oil to wash the disks. I would think a clean
room would be in order, because even fresh oil will cause anything to
stick to it.
?The good
news is I am pretty sure that lubrication was introduced with the IBM 3340
(Winchester)
The more good news is that I think 3348s were the only packs to use
lubrication, and maybe the 3344s, which were just 3348s you could not
remove. The more more good news is that 3348s are pretty bulletproof,
even when the seal breaks.
so the 2315, 2316, 3336, 3336-11, SMD and their DEC
equivalents
(RP0x, etc) were not lubricated.
I might as well say that I am looking for IBM 1316, 3336, and 3348
packs - even crashed ones.
If you are real careful you can disassemble and
reassemble a servo type disk
pack so long as you are very, very careful not to move (or replace) the disk
containing the servo pattern!
If the servo info is on one disk of the set only (I think it is on
most, but I could be wrong), it seems to me that the position of the
data platters would not matter anymore, as long as nobody cared about
the data.
Another idea - now with video cameras getting tiny, I would think that
one could make an station that could inspect a multiplatter disk
without any need to take the pack apart.
