A Terabyte of Data on a Regular DVD...

[b1gapl]

"This is the promise of the 3-D Optical Data Storage system developed at the University of Central Florida (UCF). This technology allows to record and store at least 1,000 GB of data on multiple layers of a single disc. The system uses lasers to compact large amounts of information onto a DVD and the process involves shooting two different wavelengths of light onto the recording surface. By using several layers, this technique will increase the storage capacity of a standard DVD to more than a terabyte."

...pretty insane...

Pretty cool,I always though 4GB is not enough

So will current DVD players be able to read this? If so, that spells the death of Blu-Ray and HD-DVD

No.

No, it needs the multiple coloured lasers.

Also, do you mean "regular dvd"? I wouldnt have thought that a regular one would be able to do this, and that you would need dvds designed for the job...?

yeah, this isn't exactly a regular DVD.

anyway; the idea of blue ray is that a blue laser has a smaller wavelength, so it uses less space to read and write data on the disk.

This is the newer technique:

The process involves shooting two different wavelengths of light onto the recording surface. The use of two lasers creates a very specific image that is sharper than what current techniques can render. Depending on the color (wavelength) of the light, information is written onto a disk. The information is highly compacted, so the disk isn't much thicker. It's like a typical DVD.

The challenge scientists faced for years was that light is also used to read the information. The light couldn't distinguish between reading and writing, so it would destroy the recorded information. Belfield's team developed a way to use light tuned to specific colors or wavelengths to allow information that a user wants to keep to stay intact.

It won't compete with blue-ray. At least not yet; it'll be at least a few years before it reaches the market, if it even does at all.

BTW, I saw a Blu-Ray DVD writer for a PC in the Future Shop flyer (Best Buy to you Americans), and it costed $600. Writes in 4X. Watch for a 16X Blu-Ray for $300 in 2 years.

Hey, for $200 more, you can get Sony over LG. Or as I would say, a bad battery over a good battery

In 2 years, people will be laughing at Blu-Ray and HD-DVD.

Also, those drives don't have batteries.
