Philips, the consumer electronics manufacturer that helped invent the Compact Disc, is demonstrating a new protoype technology that can store up to one gigabyte (GB) on a three-centimeter-diameter disc. Most CDs store up to 650MB of data on their 12-centimeter-diameter media surface. The storage increase is achieved by using a blue laser as opposed to the red ones found in current CD and CD-ROM readers. A standard-sized CD using this technology could store a whopping 27GB of information.
