Laser breakthrough could soon enable 1-TB optical storage
SENDAI, Japan – Numerous research labs are looking for ways to increase the amount of information one can store on a CD-ROM or related optical disc, but the equipment needed to push past the boundaries of Blu-ray technology is exceedingly large and expensive. Recently, investigators affiliated with Tohoku University and with Sony Corp. in Atsugi have made a huge leap toward a laser that is portable yet potent enough to drive optical storage up to 1 TB. Researchers at Tohoku University and at Sony Corp...
