"Pioneer has introduced a sixteen-layer Blu-ray Disc capable of storing 400GB of data, as of July 13, it was shown at the International Symposium on Optical Memory and Optical Data Storage 2008 (ISOM/ODS2008). This holds eight times more data than the current dual-layer 50GB version currently in use on the majority of high-def movies, and double the space of Hitachi�s last eight-layer Blu-ray.
The disc is currently read-only, but Pioneer says it is backwards compatible with existing Blu-ray players on the market.
A new disc structure was developed to reduce crosstalk from adjoining layers, making it able to access all sixteen layers at full bandwidth. Each layer contains the standard 25GB currently available with Blu-ray Disc.
Now to the nice stuff, the price, well just think of it as buying 3 playstation 3�s the Disc is to expansive for the public at this time and there is really no need for it unless you need to move a server�s worth of data from one to another."
