Actually, if ya wanna go techno-retro - we found
(MGM Studios /
Library
of Congress / Filmbond Archival Institute) that the
most long-lived
medium
for this kind of work is optically encoded data on
well-processed
Mylar
linear film of some kind. With proper encoding
techniques, one can
get
bit densities of more than a megabyte per inch - of
standard 35MM
sprocketed stock - of course an order of magnitude more using 70MM -
and
even more if wider stock is used.
So our discussion a few weeks ago about film resolution was relevant
after all ;-)
