Pioneer developed a Blu-ray disc compatible disc that can hold 400GB of data on 16 layers. The company for now only has a read-only disc available but expects that it will also be able to produce recordable discs. Each of the layers can hold 25 GB of data, the equivalent of one singel Blu-ray disc layer.

Multi layer discs exist for a while. Normal DVD players and burners are usually able to read and write to dual layer discs and also with the introduction of Blu-ray there was a lot of talk about multiple layers straight away.

It has been a challenge for Pioneer to get a clear signal from each of the recording layer of the disc, in such a way that the data was read straight from one layer with no distortion of data from other layers. Pioneer invented a disc structure that can reduce crosstalk from adjacent layers, resulting in a 16-layer optical disc that can playback high-quality signals from every layer. 

Pioneer 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. Since the optical specifications of the objective lens, such as the distance from the lens to the disc, are the same as those for the current Blu-ray discs, it is possible to maintain compatibility between the new 16-layer optical disc and the Blu-ray discs.

As usual with these kind of technologies, no data on availability and pricing has been given.

Something tells me that with 16 layers, you might be very lucky to get single speed avaraged across the entire disk.... :r

16 layers? It'll be a while before they have a recordable one available. And you can bet it'll be pricey. And once you've coastered a few I bet the neato factor will drop off fast.

getting closer to a usable size... maybe we might see 1TB. Then I might start getting happy.

I'm guessing you'll need to buy new hardware, too. Damn.

Duke, not according to the article "Since the optical specifications of the objective lens, such as the distance from the lens to the disc, are the same as those for the current Blu-ray discs, it is possible to maintain compatibility between the new 16-layer optical disc and the Blu-ray discs."

Would you want to archive your preciouse data to one of these? A 1TB HD will be far cheaper, quicker and reliable..

Why on earth would anyone want to backup their precious data to something like an optical disk is beyond me. Yes, I have done so in the past, maybe 5 years ago I was still burning data to DVD. Now ? I use hard-disks. Safer, cheaper, quicker, and generally just better. I don't know anyone with a blu-ray burner, as the cost per gigabyte is just stupid - you'd have to have more money than sense to waste your money on optical junk. I could never truly trust my data coming off an dvd / or any other optical format.

LOL, what a wothless announcment. They cant even get the regular Blu Ray discs to sell on the storage side of the market, like this thing is gonna change anything, lol. People still arent even using Dual Layered DVD9's because of the high prices of the discs compared to the single layered discs. Single layered DVD's account for over 98% of all storage DVD's sold. if people were that hard up for additional storage space they would have moved to DVD9's and again they havent. People are more concerened with cost per GB more then they are with size and people are 100% content to use SL DVD's. The only people who will use Blu Ray storage are people in certain creative fields and some people who have too much money and nothing worthwhile to do with it. Blu Ray on the movie side at least will obtain niche status and make a llittle bit of money. Blu ray on the storage side is going to be an utter failure.
