In the News What stands a better chance of surviving 50 years from now, a framed photograph or a 10-megabyte digital photo file on your computer's hard drive? The concern for archivists and information scientists is that, with ever-shifting platforms and file formats, much of the data we produce today could eventually fall into a black hole of inaccessibility.

CD's last forever ?

I remember when we were told that CD's would last for all our lives, and well, i rescued some of the first CD's i burned 10 years ago, and the had become almost transparent, and obviously, they couldn't be read and i had to throw them away. And i was a bit angry because they contained some music i download via dialup i wanted to listen back ;)
I feel hard disks are much safer, but i don't know if they will last longer than 10 years or so.

Pressed CDs are supposed to last a hundred years or so, but of course they haven't been around long enough for us to know their actual usable lifespan.

you are not up to date on this
now it's known that after 20 years the polycarbonate has degenerated enough (microcracks and so on) that you have to rely on errorcorrection to read a disk in perfect condition
but thats with the large structures in cds
so how long will a dvd last? 10 years?
a bd? 5 years?
we will see...

the problem i see with hardrives is that if the read heads or control electronics dies, there is just no way to take the plates out, pop them into a new case and power back up.

with a optical disk you do not have any dedicated read hardware. any optical drive that can read the format will do.

now the survivability of the disks themselves, thats a whole different story...
