Laminated 400GB DVD coming soon
Sixteen Blu-ray discs glued together
PIONEER HAS DEVELOPED a 16-layer read-only optical disc with a capacity of 400 gigabytes.
The laminated disks, which are effectively 16 layers of 25GB each sandwiched together, could go into mass production soon.
Pioneer has managed to reduce the cross-talk data transmission loss which has previously plagued multi-layer optical media using new production technology which it has developed alongside its traditional DVD manufacturing.
The company has achieved stability in the playback of recorded signals by employing 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', apparently.
And because each layer of the disk has identical specifications and characteristics to a standard Blu-ray disk, backwards compatibility should be a doddle.
Pioneer will present the details of this research at the International Symposium on Optical Memory and Optical Data Storage 2008 to be held in Hawaii from July 13. µ

Historical
And of course when popped in the player the thing will be too thick and be scratched into a 16 layer coaster :)Perhaps it's now time for MS to add blu-ray to their xbox360? (If you catch my drift.)
Finish your research....
It's not a DVD, it's a BD. it's like saying 10 years ago that "a new high capacity CD is coming out" when talking about a DVD. BD's use different technologies than DVD, mainly a shorter wavelength of laser letting the dips in the surface that are read be closer together. Now, a 400 GB DVD? that would be quite massive, with almost 100 layers.....yawn
didn't Maxell complete testing a 1Tb disk a year ago. The there was that other company who have roadmapped 5Tb on a disk. There's no point in adding something as obsolete and overpriced as blueray to a 360 or anything else - Blueray is as dead as HDdvd !!With 16 layers...
...who needs a DVD anymore? Use a small laptop HD for the same size? Or solid state RAMHolographic Quits.
Holographic Disc Has Gone Under, Terminating nearly all engineering staff after reading of 256 layer discs, few months back. So this must be last shot. if you muxtiply, mux? its about 6.4 terraflops, well it is possible. Why?Have You ever looked thru Microscope at those little swiming bugs? Just slightest turn of Microscope focus wheel & WOW, Bug on Bugs, You Can Quickly Change Focal Plane seeing things In Focus, Just thousandsth of inch apart.
So this will undoubtly change Data storage & Reduce Prices tremendously. You can cram 1,500 DVD Full length 2 Hr Movies into ONE Disc, making Movies On Demand IPTV Much More Likely. Instead of Warner Time, Whopper Time.
Get You Pencils out &: GO FIGURE.

Meh
Where's my HHDDVVDDBVD already?That's all I'm worried about =P
But why
If it's entirely read only, it's not going to be much good to anyone now, is it.Read only?
What use is a high capacity read only disk, what are they going to put on it? 16 HD movies? MGS4 Directors cut? Entire TV series?Maybe if it was writeable I'd care, I could back up my entire HDD.
Just in time...
for Windows 7 distribution. Probably two of these disks.I would not dare burning
my precious data on such multi layer disks any time soon. With single layer disks having a half life of about 5 years, the 16 layers ones with "aberration compensation" mechanisms and noisy weak signals would be too much of a risk.Can you imagine how long that would take to install, ffs!
After spending "ages" installing a 2 DVD game, I dread how long it would take to install a 400GB game.Hey, maybe the local Chinese DVD sellers can sell 1 x 400GB disc with 30 movies on it, or £25k worth of software? lmao.
You guys are annoying me
First of all, when the term DVD was created, it was supposed to an acronym, it either meant Digital Video Disk or Digital Versatile Disk. Well, both those phrases can accommodate the idea of a Blu-Ray DVD. It could accommodate the concept of CDs, too, if the term DVD had come sooner.And, in response to the person who doesn't think anything good could be put on these things: What about Hollywood movies? And it wouldn't have to be exactly 16 movies, or even less than 16, they could have a movie span two different layers if they planned ahead. So, more like 20-40 movies. How many disks would it take to create the most popular movies of the last 30 years or so? 5, 10? And you could base the discs on genre, too, if someone was into romantic comedies, then they could get a disk packed with romantic comedies. How could this be profitable, you ask? Simple...
It would work like a rental system, except you wouldn't have to leave the house or download anything, you'd just pick what you want and watch it. If you wanted to, you could own a movie, but you'd still have the same number of disks. If a disk got scratched, no big deal, they just send you another one, since the DRM is on the DVD, you'd only be able to watch what you paid for. There'd be little codes associated with each movie, and that would decide what you could watch.
The reason DRM around now is easily breakable is because the consumer has more rights than they think. If someone has the initiative to sue a company, then they certainly have the initiative to get on the Net and figure out how to crack the DRM. DRM isn't there for security, it's there so they can cover their asses. Simple case of them considering all the angles. If you can crack the security on your own, what's the point of a Fair Use lawsuit?
Size
So they'll use one of the layers for the actual movie, and the rest of additional 14 layer space for encryption / security system? ;-)Too much detail...
That's a level of pornographic detail I don't need to see!Great For Your Porn Collection
Wow! This will be just AWESOME! Now, I can backup my porn collection. Hell Yeah!Let's see here...yes, I will need a total of 57 of these disks for my small collection of honey buns. Hope it won't take long to burn one of these thangs. I guess I could pass the time if it does by downloading some more huns for my collection. Hell Yeah, that's fo sho!
All deez external hard drives full of my prons startin' to get a little crowded up in here! Deez disksises will sho-nuff be a big space saver that be fosho!
Anyway, I'd like to thank evabody for reedin' my postises...my we has us sum world peace!
Free at last, free at last, GOOD GOD ALMIGHTY, FREE AT LAST! That Benjamin Franklin was da man!
@Jason Goatcher
Good job there Jason. I'm sure your bosses at the MPAA are going to give you a nice raise.Unfortunately for you, DRM is undefendable from a consumer point of view, so your arguments are mostly falling on very deaf ears.
it would take long time to burn
well if i start the buring at age of 19 i will be 99 when the burn finishes
