Judy,
Film might work pretty well. As I recall, mylar base B&W film has a lifetime
of at least 100 years. That's what libraries use to make microfilm and
microfisch. The digital data could be recorded of that.
Of course, you would need a recorder and a playback device.
We put several hundred VHS tapes on VCD using CD-Rs. The best thing about
digital as opposed to analog is that you can make copies that are as good as
the original.

I don't think so. Clearly digital underpins a <br>>great deal of
