DiscT@2 technology

After several years in development, it was in the summer of 2002 that Yamaha Electronics introduced its innovative DiscT@2 technology. This allows a CD-RW drive's laser to tattoo graphics and text onto the unused outer portion of a CD-R disc, thereby providing a far more professional looking disc labelling system than possible by use of stick-on labels or felt-tip markers.
