There is a large literature on these issues.  One source is this:
I can't vouch for how good or up-to-date that is, but there are 
certainly people worrying about how to solve these problems.

BTW, there are basically two approaches for the hardware aspect of this 
1) Maintain hardware to read the old tapes, 8" floppies, etc.
2) Migrate the data to new media.
There are also software issues, like how do you read a Wordstar 1.0 
document once you have it from whatever media you stored it on.  Storing 
documents as LaTeX source is one approach, presuming you can do 
something with LaTeX (or at least make sense of the markup) a thousand 
years from now.  In general, though, XML is the currently preferred 
markup for archiving text documents.  (Binary documents, such as images, 
are obviously a much bigger problem.)
