Verbatim Spins Out Dual-Layer DVD+R Discs

"The first dual-layer DVD+R recording media are set to go on sale in Japan at the end of this month and in the U.S. in June, says disc maker Mitsubishi Kagaku Media.

The discs were developed jointly by Mitsubishi Kagaku, which uses the Verbatim brand name, and Koninklijke Philips Electronics NV. The discs offer 8.5GB of recording space compared to the 4.7GB of space available on a standard DVD+R disc.

They will cost around $13.30 per disc in Japan, said a spokeswoman for the company."

How It Works

"As the name suggests, the extra recording capacity is made possible through the addition of a second recording layer inside the disc. To make it possible for a single laser to access both recording layers, one behind the other, the top layer has been made semi-transparent. That allows enough reflectivity for data storage and playback while also allowing light to pass through to the second layer.

Similar technology is already in use in commercial DVD-Video discs and so is supported by almost all DVD drives currently on the market. The dual-layer discs should be compatible with any drive that supports these discs, according to Mitsubishi Kagaku."

$13 a Disc... hmmmm. At that price the media will never catch on - Blue ray or something better won't be far behind. I know its an introductory price but I suspect the movie industry has their hands in that jar somehow.
