Pioneer Creates 16-layer Disc With 400 GB Capacity

[Guest]

A new generation of high capacity optical discs could be on the way as Pioneer claims to have developed read-only disc media with 16 layers and a total capacity of 400 GB.

Wow... imagine burning a disc with like 95-100 4GB HD movies. Mmmmmm must have this and have it be writeable.

However, multiple layers weaken signals from each recording layer and the industry has found it to be increasingly difficult to receive clear signals in a stable manner within multi-layer discs due to crosstalk from adjacent layers and transmission loss. Pioneer claims it has solved this problem using a disc structure that can reduce crosstalk from adjacent layers as well as a wide-range spherical aberration compensator and light-receiving element that can read out weak signals at a high signal-to-noise ratio in the optical pick-up mechanism.

Reduce. What are the metrics from the original and from the Pioneer? They should try transparent media and use flourecing dyes... oh wait, it's already been done, quite successfully if I may add. It's called Fluorescent Multilayer Disc. Too bad since the powers-that-be purposely placed it out of reach of the consumer. Think of all the movies we can put in it if it were made available to the general public.

Sigh
