Pioneer is developing a 16-layer Blu-ray disc that has a capacity of 400GB, claiming to be the first of its kind.
The discs feature 25GB per layer, which is the same as a Blu-ray disc. This multilayer technology will also be applicable to multilayer recordable discs.
The lens specifications are the same as existing BD discs, making it possible to be compatible with existing Blu-ray players.
Pioneer uses a technique that reduces crosstalk from adjacent layers. The result is a 16-layer optical disc that plays high-quality signals from every layer.
Pioneer will release more details on July 13 in Hawaii at the International Symposium on Optical Memory and Optical Data Storage.

That's very cool, especially the fact that it could be backward compatible with existing players (I assume after firmware patching or other updates?).
Imagine the content possible on 400gb optical discs. You could publish entire high-def movie collections on a single disc.
Bodes well for games, too. Even the latest games don't require anywhere NEAR that much data. You could have PS3 games completely uncompressed on disc, which would mean improved load times and performance.

i read about this on joystiq.com and some other websites. every place that had an article said something different as to whether the existing players would be able to read them. some said yea, others no.
400 gb on a disk boggles my mind. i remember my first computer was packing some serious disc space when i got it and it only had like 60 gb of space on the hard drive. now there going to be discs that hold as much as five of my 80gb ps3's
no sense in sugar coating sh*t. sure it makes your initial reaction one of "ooh and ahh," but sooner or later all your left thinking is "AWWW SH*T!!"

Something I'm worried about, 400GB on a single disk is great and all, but they better put some kind of hard, anti-scratch coating on that disk otherwise 400GB of data could be lost.

Heh, my first computer had I think 80MB of HDD space and 6MB ram after I upgraded it. 486sx 25mhz.

My first computer (still have it somewhere) was this: A Compaq STE/286 "laptop" (heh)
The keyboard was full size minus numpad and was actually removable with normal style adjustable legs. It required an external mouse for use with windows windows (none built in). Mine was running DOS and Win3.11.
Stats: 12mhz 286 processor 2MB RAM 40MB HDD space (almost half of that occupied by Windows) Monochrome display (with absysmal refresh rate) 3.5 inch floppy drive (a full 3.5'' bay sized one like you'd use in a desktop computer) I ran Ultima I on it. That's the only game I ever remember installing on it, though.
Oh that's funny!
