Title says CD, but it's actually a DVD. Still extremely impressive.
- ctdonath 12y agoIt's not a DVD. Point is it's a 5.25" thin polymer disc of some hole-based storage media. "CD" and "DVD" are used just to make muggles get the idea.

The researchers never used any discs. The 1000TB figure was for a surface area equivalent to a CD or DVD; they're the same physical size, and these descriptions give the reader an idea of what a 9nm feature size means in practical terms. What they actually developed was a novel resin and a method for etching 9nm dots in it using a specific optical laser setup. If it were to be commercialized, it'd be a new type of disc, and CD/DVD lasers would not be able to read it.
