CD made of “optically tempered ultra precise glass”

Every company wants to have at least one product in their portfolio that they can claim to the world’s first, world’s slimmest, world’s fastest, and or world’s smallest. Fine NF Japan’s claim to fame, apparently, is the world’s first CD made of glass. The ultra transparency is said to prevent any warping or distortion, and as a result, you get “crystal clear sound and super high treble quality.” Really? The CD doesn’t look all that clear to me.

Now, they couldn’t just use any old glass to achieve this; Fine NF Japan implemented “optically tempered ultra precise glass which is used in telescopes and camera lenses.” This innovation naturally comes at a price, and it’s a hefty one: these glass CDs run US$830 a pop.
