That is very true, and it is hard to believe that even after all these years no one has yet to invent a real storage media that is 100% reliable for archival of data.

If you think about it, glass pressed media is really the only safe archival method. They contain real pressed data tracks that cannot degrade over time. The only possible way to damage them is scratching the disks. So the logical solution would therefore be pressed DVD-Ram disks in the cartridge format, as that would protect the disk against damage. Sadly I don't think cartridge DVD-ram is really used much these days.
