Does anyone have pointers to factual discussions, information or
studies about how long various storage media are expected to last,
particularly (and for example) magnetic tape, magnetic disks, and
optical storage devices?

Acid-free paper should last for a millennium (at least). Is any
electronic technology as durable? (It would be odd if that kind of
storage time could only be achieved by transferring data from magnetic
or optical media to some kind of acid-free punch card!)

E-mail responses preferred.

Thanks in advance.
