The Braille CD-R is a great idea from Mitsubishi. It allows blind people to know which CD they are holding and in turn, makes it easier to find the music that is wanted. The Braille bumps are created from high viscosity ink which has a height of 0.1mm from the surface of the CD. This is small enough to not get jammed in the drive, but large enough to be able to feel the Braille marks on the disc. The technology is currently compatible on CDRs and it shouldnt be a problem to port the bumps to DVD, HD-DVD and Blu-Ray discs also.
I am surprised that this wasnt thought of long ago with CD just hitting its 25th birthday recently.
