ZD’s emerging technology blog has a piece on some new research that combines the usage of lasers at different wavelength, allowing recording on multi-layer DVD technology and storing up to 1 terabyte of information per disc. Even more impressive is that the technology doesn’t require the use of those expensive & rare blue-ray diodes.
“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.”
But.. all is not good news.. how long before we’ll actually see this technology?
“But when will we able to use DVDs with a terabyte capacity? Not before several years. In fact, the researchers just received a $270,000, three-year grant from the National Science Foundation to continue its work.”
Yeah.. it’ll be a while.
