SONY, in partnership with Tohoku University, said it has developed a new laser technology that will allow it to encode discs with 25 times more data then a standard Blu-ray disc.

Each of the new discs will have a total capacity of one terabyte, or 1024 gigabytes.

The all-semiconductor laser technology uses an extremely condensed wavelength of 405 nanometres and generates high-powered optical pulses at three picoseconds, or three-trillionths of a second.

Technical details aside, this ultimately could mean big things for a next-generation disc format, particular for high definition films, television and video games.

Currently a standard dual-layer Blu-ray disc provides 50 gigabytes of maximum data capacity, which is rarely ever reached by games or movies. However, with up to one terabyte of data at their disposal, publishers could pack multiple titles - up to 50 HD movies or entire seasons of television series - on a single disc.



The potential applications for video games are also substantial. With more space comes more capacity for more elaborate graphics, longer games, uncompressed multi-channel audio, more elaborate gameplay, or multiple games on a single disc.

Some dill will probably invent a camera that shoots at corresponding resolution as well *shudder* my PC is having enough trouble with AVCHD as it is...

Super 8 forever!

... or instead of packing more titles onto a single disc, they could also use this space to provide the titles in a matter that deserves the name "HIGH definition"... but I fear that the industry will stick to providing compression artefacts as their motivation isn't to provide quality, but to make money...

And let me guess... films offered on this super blu-ray disc will cost $5/£5/€5 more than a regular blu-ray disc. They'll offer "crisp and dazzling" 4K resolution that requires a new TV set (very large and expensive, of course). They'll also be encumbered with DRM that makes me a criminal when I copy it to my hard drive to watch on my computer-based entertainment system.

No thanks. The largest TV we could sanely fit into the corner of our living room is 32". It's bloody hard to see the difference between Blu-ray and DVD from my favorite spot on the sofa, so there's no point in pushing the resolution higher unless everyone sincerely wants a TV that fills half the room.

Quite right.. the only SERIOUS justification for such an advance is for LARGE screen presentation....IF you can find a video projector capable of handling it!
This is of more interest to the professional cinema than for domestic consumption.

Impressive resolution and data storage aside, I wonder how reliable they would be for long term storage of data. Ive heard that the files that you burn on to a DVD-R are only readable for about 5 years or so....pretty disappointing. And I have a number of CDs (containing scans of still film images of mine) that don't seem to be read by computers anymore....and they are not much more than a few years old.

There is a lot of purposeful confusion created by the DVD industry about the longevity of discs, be them DVD or BluRay, etc. You often hear that DVDs are supposed to last 100+ years and then you also hear about people with DVDs that are only a few years old that won't play any more or have corruption, etc. What a lot of people don't realize is that a commercial DVD of your favorite movie and a DVD that you make yourself have two totally different life expectancies because they are made with two different processes. Commercial DVDs are mechanical devices, like a 45 vinyl record. They are, for all practical purposes, "stamped" and have millions of tiny pits and peaks in them that represent the 1s and 0s of the digital information. Like a record from 100 years ago, these will pretty much never wear out from regular usage. Only damage from mishandling (scratches, etc) may affect the playability. But DVDs and CDs that you make yourself employ a photographic process. A laser exposes the sensitized surface of the writable DVD or CD and creates a series of black dots. These fool the DVD player into seeing them as pits and, thus, you can record digital information. But, like any photographic process, the sensitized area can eventually foul over time. I have actually seen the lamination start to peel on a DVD made only a few years ago. Unfortunately, the DVD industry often uses the longevity of imprinted DVDs when they boast about how long a disc is expected to last, which is very misleading. I haven't been burning BluRays long enough but I suspect they will eventually have the same issue as will the latest storage device, if it works the same as current disc burning technology.

For me, 1080p is far good enough resolution for home viewing and projection, even on big screens. Most prints you see at your local cinema have not much more than the equivalent of 1000 lines.

Instead of increasing resolution, we need better color depth, true anamorphic scope and that kind of things that make a digital image closer to real film. But these days, the only thing that sells is the word "resolution". Too bad...
