When I was fairly new at the CD-R thing, I began
purchasing what was
then known as Mitsui Gold media, which claimed a lifetime of 300
years. I can still read what I wrote then just fine--but so can I
also read the stuff written on bargain-basement "blue" CD-Rs.
How old are CD's at this point? 25 years seems about right.
I got an 8" floppy in yesterday from a machine
shop operation who
needed their software rescued. This was Maxell "R-V" floppies;
something like "Reliable and Verified".
I also rescued some 8" floppy files about 15 years ago. I can't
actually remember, but I think I might have had to completely
discard the jacket. Of course, since that was a rescue and the
files ended up being returned by e-mail, the media was no longer
important.
Has anyone else read floppy media sans jacket?
This makes me wonder how many years a "1000
year" CD-R will have on it
before the substrate disintegrates, rendering the medium unreadable...
I have DVD backups from 10 years ago, but I am confident
that DVD backups exist that are much older. 10 years ago,
a DVD burner was still rather expensive, so I shared one
since I only burned a backup every four months.
