I never really believed that the label side of a CD is the weakest bit. Until today. I took to scraping the label side off the top of a recordable CD today. It took five minutes. The CD is now completely see-through and no longer works as a CD. Try it with a dud CD one time – they are soooo weak. Always place your CDs label side up when leaving them lying around. Scratches to the plastic do not harm as much as scratches to the label. You learn cool stuff everyday huh? How CDs work.
