Hey, I thought everyone here should read this... Apparently those CD-r's we buy at the store only last on average 2-5 years... http://news.yahoo.com/s/pcworld/200...XNnFQWs0NUE;_ylu=X3oDMTA3ODdxdHBhBHNlYwM5NjQ- Optical discs commonly used for burning, such as CD-R and CD-RW, have a recording surface consisting of a layer of dye that can be modified by heat to store data. The degradation process can result in the data "shifting" on the surface and thus becoming unreadable to the laser beam. "Many of the cheap burnable CDs available at discount stores have a life span of around two years," Gerecke says. "Some of the better-quality discs offer a longer life span, of a maximum of five years." Distinguishing high-quality burnable CDs from low-quality discs is difficult, he says, because few vendors use life span as a selling point.
