How Long Do CDs Last? It Depends, But Definitely Not Forever : All Tech
Considered : NPR

Back in the 1990s, historical societies, museums and symphonies across the
country began transferring all kinds of information onto what was thought
to be a very durable medium: the compact disc.

Now, preservationists are worried that a lot of key information stored on
CDs — from sound recordings to public records — is going to disappear. Some
of those little silver discs are degrading, and researchers at the Library
of Congress are trying to figure out why.

In a basement lab at the library, Fenella France opens up the door to what
looks like a large wine cooler. Instead, it's filled with CDs. France, head
of the Preservation, Research and Testing Division here, says the box is a
place where, using temperature controls, a CD's aging process can be sped
up.
