Copyrights and CD-Rs Endanger Audio History
SEWilco writes "A study by the Library of Congress has found that many audio recordings are being lost due to copyright restrictions and temporary media. Old audio recordings are protected by a various US state copyrights, so it's hard for preservationists to get and copy material. Recent data is threatened by being put on writable CDs, because CD-Rs begin to lose data after a few years, so recordings from as recently as 9/11 and the 2008 elections are already at risk."
I have some optical media that's from ~2001. Most of it's just fine, even after a tortured life. I trust high quality optical media more than anything else.
CDs are rarely an all-or-nothing affair. Even if you do lose data, you tend to not lose it all in one freak accident, not to mention solid state and magnetic media make fantastic paperweights after a solar storm.
