Every time the density of storage media increases, this issue is (and
probably needs to be) revisited. I figure, with each doubling of
storage density, there should be a doubling of reliability and
permanence, since we are at least doubling our confidence in the product
with the amount of material going onto it.
I do believe optical is better than magnetic, and if kept relatively
safe of optical damage (from UV, intense lighting, etc), if the media is
quality, it might even last a few dozen years... However, coming up
with multiple formats for the same media almost always creates all sorts
