Pioneer has gone all storage crazy on us by coming up with a Blu-ray disc that is capable of holding 400GB of information.
This disc uses 16 layers to hold all the information at 25GB per stack, compared to the dual layer 50GB discs that we see in Blockbuster but never rent because the normal DVD is, well, cheaper.
The process of manufacturing such a disc is difficult, as the layers used often want to all be heard at once, so interference is common.
But by using techniques from the DVD manufacturing process, Pioneer has apparently solved the problem.
Backwards
According to the Japanese company: "Since the optical specifications of the objective lens…are the same as those for the existing BD discs, it is possible to maintain compatibility between the new 16-layer optical disc and the BD discs."
So this means you can probably pop one of these big-boys into your newly purchased Blu-ray player and still access all the large space optical goodness when released.
Pioneer has promised more information on the new technology at the Symposium on Optical Memory and Optical Data Storage 2008, which sounds thrilling, on the 13 July. | | | | Signature banned: Reason out of date... |

| | Posted: | | | | Of course, the only logical use for a 400GB disc is for data. On the movie end of things, it's the equvialent of HD DVD coming up with a 51GB disc with only 30Mbps throughtput. It doesn't help...except in professional and personal data storage (i.e. backing up hard drive, etc).
This would be amazing if the PS4 has a BD writer in it. And, of course, it's amazing for the computer industry. | | | To err is human...

| | Posted: | | | | I wouldn't worry about it. Studios have shown little inclination to actually utilize the full storage space available on any format...unless they're putting out a quadruple-dip budget release for the dump bins. | | | | Last edited: by mdnitoil |

Not to mention that these would be great for TV series! Nope. You only get 48Mbps sustained throughput will the Blu-ray standard. For higher resolutions (like 2160p and higher), you need MORE throughput. TV series would benefit from 200GB BDs, but most likely not 400GB BDs. How many TV series on BD have more than 4 - 50GB BDs? I don't have any AFAIK. | | | To err is human...

| | Posted: | | | | I am pretty happy with what I get on a Dual Layer BD these days. Until they come up with TV's with a much higher resolution I really see no practical use. Except maybe for the, mentioned by 8ball, use of putting an entire season on one Disc. Then again, how would they justify the high price if it's just one Disc? | | | | Check out my Youtube channel under https://www.youtube.com/user/alittleolder |
