Yamaha's DiscT@2 technology allows the user to burn text and graphics onto the data side of a CD-R disc. This innovative process eliminates the need for cumbersome stick-on labels, which peel off in heat, become illegible when wet, or cause the CD to spin unevenly, as well as the use of felt-tip markers that could smear and are unprofessional at best.
It'll be interesting to see how visible this is up close. It wouldn't be that impressive if you had to angle the CD at a bright light to see anything.
