Exactly a year and five months after Toshiba brought an end to the high-definition disc format war, the Japanese consumer electronics company confirmed its plans to produce its own Blu-ray Disc player. Previously, rumors trickled in about Toshiba considering such a move; Japanese newspaper Yomiuri Shimbun this weekend reported that Toshiba will adopt the format it once battled against.

General Electric Global Research says it has figured out a way to put up to 500GB of data on a regular-sized DVD disc under laboratory conditions. GE says its breakthrough was achieved by writing 3-dimensional patterns that represent data onto a disc made of highly reflective material. The disc then acts as a mirror that makes it possible for a laser to pick up the entire piece of data. GE's process doesn't just put information onto the surface of the disc--as DVDs and CDs do--but etches the micro-holographic patterns below the surface of the disc as well.

Will Blu-ray finally get some respect? The high-definition optical disc format has long been the whipping boy of media pundits, many of whom predict consumers will spurn Blu-ray and gravitate instead toward video-on-demand, online download, and movie streaming services. Blu-ray is old school, they say, a relic of the bygone era of physical media, despite the fact that it bested challenger HD DVD in 2008 after a two-year high-def format war.

There was a time when it looked like HD-DVD would be winner in the battle to bring high-definition to computers and video players. Then the momentum suddenly swung to a competing standard called Blu-ray. Now, it looks like Blu-Ray is in trouble, but not from HD-DVD.
