>If you put a blindfold on, would you be able to tell one CD from another?
>That's pretty much what blind people have to deal with all the time.

>To create the Braille dots, Mitsubishi printed the labels with two layers
>high-viscosity ink, which allowed for characters to protrude up to 0.1

>with extra-smooth ink so the dots stand out as much as possible. Great

>for now. You could get special ink for Braille labeling, I suppose, but it's
>doubtful there would be enough demand for the industry to offer it.

>Of course, there's no reason this technology couldn't be used for DVDs and
>other media, so expect more Braille discs to come down the pike soon. -
