Sony and Panasonic Propose Blu-ray Disc Capacity Increase

500°
224w ago - Sony and Panasonic have developed a new technology that will allow the layer capacity of Blu-ray disc to be increased from 25GB to 33.4GB per layer.

Apparently, exisiting devices would just need a simple upgrade to read all 33.4GB or 66.8GB per disc.

To quote: "Sony and Panasonic have announced that they have developed a new optical disc evaluation technology that will allow the layer capacity of Blu-ray media to increase from 25GB to 33.4GB using existing Blu-ray laser diodes.

This would presumably allow existing Blu-ray hardware - including Blu-ray Disc players and burners - to play the proposed discs with a simple firmware upgrade.

Currently, disc evaluation is accomplished by analyzing disc jitter, but at higher capacity, that technique becomes unreliable. Sony and Panasonic resolved this by developing i-MLSE (Maximum Likelihood Sequence Estimation) evaluation index, which can perform the same function as jitter but at higher capacities."
 

Top Developer Confirms Nobody is Using PS3 to Full Capacity

261w ago - I am aware I am likely to get flamed for this as due to an NDA (non disclosure order) I am unable to name the developer or the game he was working on, but I still think it is worth discussing.

Recently I travelled to see the preview demo of a hugely anticipated game coming out later this year. Once we had viewed the demo (which was interestingly given on Xbox, usually developers choose PC) we were allowed some one on one time with the technical guy to talk about the development of the game.

I am not claiming to be a tech head in any way but I was interested in what I had been reading about developers not using the PS3 to it€s full capacity. As these guys had just developed an all new engine it seemed a fair question to ask him. My question was put like this:

€A lot of people say that game developers are not using the total capacity of the PS3. What have you guys done, if anything, to try to use the full potential of the machine in this new engine design and in this game€

His answer, transcribed from my dictaphone was this:

€I do not think we will use the full potential of the PS3, no other developer has done so far. It is new technology and a different structure than we are used to working with. But I think we have used the PS3 very well. We have used SPU€s,...
 

Bilkent Tech to Make DVDs with 1,000 Times More Capacity

300°
262w ago - The Bilkent University Nanotechnology Research Center (NANOTAM) has developed a new technology that enables DVDs to store more than a thousand times as much data as those currently on the market.

Developed by Dr. Ekmel -zbay, the head of NANOTAM, and students -zgür Attila Çakmak and Koray Aydın, the new nano-materials will pave the way for production of the next era of DVDs, which will be able to store thousands of movies on a single disc.

The invention by the Turkish scientists was published in one of the most prestigious physics journals, the Physical Review Letters. Dr. -zbay said they focused their studies on concentrating rays on a point that covers as small a space as possible.

€We have developed a new technology that enhances the number of rays passing through a small dot by thousands of times. With this technology more data will be stored on DVDs in a smaller area,€ he said.

-zbay said a normal DVD has a maximum capacity of 50 to 100 gigabytes and that they will increase this by at least a thousand times. €We have created a magical material which enables rays to pass through a very small point,€ the NANOTAM head noted.

The new technology permits a far smaller notch to be etched on the DVD surface with a wider wavelength. It is expected...
 

Sony lacks manufacturing capacity to meet Blu-ray demand?

50°
315w ago - Despite Blu-ray's utterly devastating victory earlier this year, Sony may be in a spot of trouble. Seems the company has a bit of a problem manufacturing the discs (I swear I've heard that before), and since it's the the biggest producer of The Blu (that's how cool kids say Blu-ray), it could be the biggest obstacle to the format€s success.

Not that that really matters, since in five years we'll have a new format. Demand for The Blu is expected to JUMP this year to 48 million units; Sony only has the capacity to manufacture 38 million, and that's after an upgrade to its facilities.

And while I'm thoroughly post-disc (technically), I did have my eye on the PS3, more or less because I could use it as a Blu-ray player.

But then I heard the system doesn't output DTS-HD, so what's the point? :P
