Consider that the Dead Sea scrolls lasted 2000+ years. They were stored
inside clay containers in a cave in a dry climate. By actually trying to
we could probably create a self-contained perpetual preservation
chamber that could probably achieve at least that.

So why bother with punched tape? Can't one get a much higher density with
optical-mark encoded paper documents?

Sure the reader will have to be more complex but unless we manage to
annihilate ourselves in the next 100 years we should have the technology
to put together an optical mark reader.

Paper will last longer than anything we've been discussing so far (save
for Mylar) but is much, much easier, and cheaper, to implement.
