I don't know about retention, but I expect I will be making a backup of the
long term files about every one or two years. Does anyone know how I
might test a magneto optical cartridge for long term degradation? Also,
if I can read the cartridge, does that indicate it is as good as when it
was written or should it always be written again after 5 years just to be
sure?
Well, I don't know for sure, but I expect they're pretty good. I know of a
local company that has ~1TB of records dating back many years on MO media, and
they use them regularly (as I understand it, anyway; I don't actually work
there) so the data's probably pretty stable...
