Las Vegas is no stranger to bright lights, but next week will see an entirely new laser show as breakthrough technology shows off 3-D storage for digital video. InPhase Technologies, an offshoot of Lucent Technologies ' research arm Bell Labs, will be showing the first commercial holographic video recorder at the National Association of Broadcasters (NAB) Show on April 8 in Las Vegas. The device uses the company's Tapestry technology to hold 100GB of data on a single CD-sized write-once disc as a succession of 1.3MB holograms. That's enough for 20 full-length movies, or 30 minutes of uncompressed high-resolution video.
