Because CD and DVD media - in 2003 more than 7,150 million CD-R discs and more than 400 million DVDR discs were made and sold -- is used to archive nearly everything today it does make you worry.

DVD drives are not only able to play and write to DVD media, but also CDs. The main difference between CDs and DVDs is the size of available storage. With a CD, you'll get around 700MB at the most.

Fuse a CD and a DVD together and you get a DualDisc, which the music industry hopes will win back buyers. MSNBC's Gary Krakow has his doubts.
