A CD - Rewritable (CD - RW) is computer data storage media that works just like a standard CD except that you can write to it over a thousand times. A CS-RW can be run in standard CD or DVD players. They do require a CD-RW drive to write to, however. Although these CDs are made from new virgin material, all the packaging is recycled - the jewel cases are made from recycled plastic and the info sheet is made from recycled paper. The finished product contains over 80% recycled content (by weight). These CDs are environmentally more friendly because they hold a large amount of information and because they are reusable. 650 MB/74 minutes. Eco Categories: Recycled, reuse, less raw materials.
