Nanoscale light tricks promise huge DVD storage
18:07 26 May 2005
NewScientist.com news service
Will Knight
The tantalising prospect of DVDs capable of holding almost a terabyte of data - or several hundred movies - has been presented in a patent issued to US storage company Iomega.

The US patent describes a disc that could store 40 to 100 times more information that a conventional DVD, using more nanometre-scale sloped ridges to diffract light. US patent number 6879556 - entitled "Method and Apparatus for Optical Data Storage" - was issued to Iomega on April 12 2005.

Conventional DVDs store information in the form of ridges and depressions, each several hundred nanometres wide. These correspond to bits of binary data - ?1?s or ?0?s. The data is read from a disc by bouncing laser light off its surface and measuring the angle at which it reflects.

The next generation of DVDs can hold almost 10 times as much data, using light with a shorter wavelength to read even smaller surface features. Two standards that use this principle are currently vying for market adoption - HD-DVD, created by Toshiba, NEC and Sanyo, and Blu-Ray Disc, from Sony.

Combining angles
However, Iomega's proposed technology, dubbed Articulated Optical Digital Versatile Disc (AO-DVD), could boost disc capacity further still. Sub-wavelength surface bumps on an AO-DVD would slope at slightly different angles - this could be used to encode up to 100 times more information.

The angles would be detected by analysing light after it had bounced off several ridges - calculating which combination of slopes would have produced the result.

Current DVDs can hold a maximum of 8.5 gigabytes - 8.5 billion bytes - of data, so an AO-DVD could theoretically hold more than 800 gigabytes. This is close to a terabyte and well beyond the capacity of most modern computer hard drives. Iomega claims the technique could also improve data transfer rates by a factor of 30.

Smaller wavelength
Fred Thomas, chief technologist at the company said researchers are working on "an array of mechanisms by which the state of a focused beam of light, upon reflection, can be precisely changed?. He added that smaller wavelength lasers would be crucial to developing such techniques.

Iomega is not alone in pursuing the idea for boosting DVD capacity, however. A similar technology is also being developed at Imperial College London, UK, although this uses the polarity of reflected light, instead of its diffraction, to detect sub-wavelength slope features.

Lead researcher at Imperial College London, Peter T?r?k, claims his approach should be more efficient, but admits that success of any system will ultimately depend on the entertainment industry. "The decision as to whether to turn this into a product doesn?t depend on us," he told New Scientist. "It depends on Hollywood."





Whoa! Imagine a disk that can hold that much data! It could be coming soon.

Should be interesting. The new "HD-DVD"'s are scheduled for release in early 2006. Although the format wars will really taint the industry. An industry standard needs to be set. While new iomega drive proposed above will be quite an achievement; it would be a shame for the discs to only be able to work in an iomega drive (for example CD-ROMS are everywhere and many companies make them).

They'll probably have a good deal of error-correction built in, just like DVDs and CDs do right now.

You can drill a 1mm diameter hole into an audio CD and not have it skip at all, I think.

They needed some time to let Blu-Ray replace DVDs, first. Once we have all gone and bought all our favorite movies in Blu-Ray...they'll come out with the "next big thing" :smirk:

I'm curious of this.  I'd speculate that the vast majority of people own TV's under 50 inches, with most owning a set below 42".  For these people, an increase in resolution will only bring a marginal increase in perceived picture quality.  I I don't think an increase in quality will be enough to drive sales of an entirely new physical media format.

Further, I think the trend is moving toward streaming technologies, and away from discs.  The increased data need will be problematic for the high resolution formats.

I think my point has already been proven with BluRay discs...

Not everyone I know has gone out and bought a BluRay player and movies, but a large proportion has! I would say it's about 50%. Not all of those people have a large TV, either (maybe one or two have a TV larger than 50"). I remember the same thing happening around the turn of the century - only a few people I knew had DVD players, but it was only another year or two before nearly everyone had a DVD player and VHS was on its way out!

True, but in previous generations (DVD and VHS), there was no alternative to physical media (e.g. no streaming).  People had to convert.  Would people still convert if there was no perceived benefit (in quality) AND there was a cheaper alternative?  Maybe not... 

A parallel might be seen in music.  People like the convenience of mp3. The non-physical, lower quality format seems to be dominating.

Despite the availability of superior music formats (CD and DVD music), people don't seem to care.

You may be right about what people will do to get their movies...but I have no doubt about Hollywood's intention to try to capitalize on a new technology. They likely will come out with another "new" tech as soon as BluRay's have market saturation.

Agreed.  And I, for one, hope they do.  I like big screens (60"+) and could use an increase in picture quality.

I still go with discs, as I feel like they have superior sound and provide a better movie experience.

I agree, I don't see it being all that useful to the movie industry.
This product would be more useful to an administrator running backups off his server everyday.
Lot less disks and faster backup time.
