Scientists have unveiled new DVD technology that stores data in five dimensions, making it possible to pack more than 2,000 movies onto a single disc.
A team of researchers at the Swinburne University of Technology in Melbourne, Australia, have used nanotechnology to boost the storage potential nearly 10,000-fold compared to standard DVDs, according to a study published in the peer-reviewed journal Nature.
"We were able to show how nanostructured material can be incorporated onto a disc in order to increase data capacity, without increasing the physical size of the disc," said Min Gu, who led the team.
Discs currently have three spatial dimensions. By using gold nanorods Gu and colleagues were able to add two additional dimensions, one based on the colour spectrum, and the other on polarisation.
Because nanoparticles react to light depending on their shape, it was possible to record information in a range of different colour's wavelengths at the same physical location on the disc.
Current DVDs record in a single colour wavelength using a laser.
The fifth dimension was made possible by polarisation. When light waves were projected onto the disc, the direction of the electric field within the waves aligned with the gold nanorods.
"The polarisation can be rotated 360 degrees," explained co-author James Chon.
"We were, for example, able to record at zero degree polarisation. Then on top of that, were able to record another layer of information at 90 degrees polarisation, without them interfering with each other," he said in a statement.
The researchers are still working out the speed at which the discs can be written on, and say that commercial production is at least five years off.
They have signed an agreement with Korea-based Samsung, one of the world's largest electronics manufacturers.
Last month, US technology giant General Electric said its researchers had developed a holographic disc which can store the equivalent of 100 standard DVDs.

This reminds me of something i think ought to be possible with film:
exposing three times on colour film with Red Green and Blue filters respectively. then printing / scanning with an appropriate light source to give three different and separate monochrome scenes from the same roll. Does that make sense? To record 3 times the info on the same strip of film (well not 3 times the info but three times more filming time - you know what i mean).
Do you think it would work?
I cant see a major reason why it wouldn't.
Sounds feasible, but then so did the holographic digital cube we were promised in the early 1990's.
there is no doubt that digital storage media capable of storing many times more data than discs we are familiar with today will come into existance. And prices, if the technology is right, will fall. Just remember how expensive CD-R machines and discs were in 1992 Did people who spent $10k on the Meridian CD Recorder and $20 a pop for blank CD-R's ever think that burners would be $20 and discs pennies?...see how they were replaced by DVDs and now Blu-Ray Discs.
The government says that by 2010 30% of us will be fat....I am merely a trendsetter

I'm not sure what using red, green and blue filters in front of color film would achieve.
On the other hand, if you were to place red, green and blue filters in front of three B&W synchronized film strips, you'd record absolutely amazing imagery. Combine them onto a single strip of color film and all you need is a time machine to be able to hop back in time and patent the Technicolor 3-strip process. ;)
I mean separately - so shoot the roll with blue filter, rewind, shoot something else with red, rewind, shoot something else with green. Telecine, then spearate the 3 channels and then make them black and white - so you have effectively got three scenes recorded on one roll of film.

Because people want to talk about how to store their films anfter the mandatory telecine.
Perhaps we could have a poll? It would be interesting to see how many shoot film only to project, and how many telecine and edit their footage with their computers. I would guess more than 50% do some kind of telecine (be it DIY or professional).

I suspect it would be more like 90%.
I transfer nearly everything. In fact, the only stuff I haven't transferred in the last five years is about six reels of random home movies. Everything else is digital, because it's so much easier to edit, color correct and distribute in digital. I just wish there was an affordable way to archive my finished projects back to film.
