CDs may not be forever! We all thought CDs would last forever! This might not be the case, there are more and more reports of music and data CDs becoming unreadable in a few short years. Some things you should know: How CDs are made: A CD is a plastic disc with a thin layer of aluminum on top and a layer of clear laquer on top of that. Data is written and read up through the plastic on the underside of the aluminum layer. Scratches on the bottom of the CD can make reading difficult, damage to the top can actually ruin the data stored on the CD. There are different grades of CDs: If you're buying the least expensive you can find chances are they're 2nd grade and probably won't last as long as you'd expect.
