Well, 20 megs uncompressed maybe, if you're talking about 25 years ago.
AIT-II is 50G native, AIT-III is 100G native...
(interestingly, the compression ratio's they quote seem to be growing... they used to quote 2:1, now they're doing 2.6:1).
Though you are looking at a substantial investment for both of those tape drives, with a < 10% duty cycle IIRC. The tapes run between 40 and 100 EUR, depending on capacity.
DDS4 is 24G compressed isn't it? I know with my usage, that would cover the
important stuff in my home directory (but not my mp3's... they can die though, I have all the CD's).

try a RAID array of the IBM 60G laptop hard drives... they should be reasonably sturdy... or just do what I do currently, and rsync your important data to 4 different machines :)

extremely light sensitive, maximal life of 20 years for the cheap stuff. very fragile IMO. DVD may be an option.. (macs can write 5G to a DVD, but you still have the fragile bit).
