(as seen on /.)
A
disc that has
10 layers (compared to a maximum of 2 for a
CD, and maximum of 4 for a
DVD.) What’s even scarier about the
disc, which is of the same size as a
CD or
DVD, is that it can store up to a massive 140
GB! That’s more than 7 times what a
DVD can store, and without having to turn the
disc! With 140
GB of storage capacity, you could fit over 20 hours of HDTV (MPEG-2 compressed)
video, a small
library or the contents of your entire
CD collection, uncompressed, on a
single 120mm
disc!
