I really hope you are backing up your data! You know all the reasons why — I don’t need to tell you. If you’re backing your data up on CDs, you will probably be interested in what David Einstein says today in his San Francisco Chronicle’s Computing Q&A column. The headline is, “Keep CDs cool so they won’t dye out”, and no, this is not a typo. Turns out that a CD’s lifespan depends on the type of dye used on the disc. Einstein’s advice is:
For best results, you should use gold discs, which are made with a very long-lasting dye. And after you burn them, keep the discs in a cool dark place, like bottles of fine wine.
He also notes that music CDs aren’t as susceptible to degradation because the music is literally pressed into them.
