p2pnet - rss feed: DVD high capacity spec approved
p2pnet.net News:- “A/V enthusiasts are salivating at the thought of discs that pump movies in all of their high-definition grandeur to their stylishly thin plasmas and LCD televisions or pricey projectors. IT pros, on the other hand, can’t help but wonder how much storage they’ll be able reclaim by backing up gigabytes of data onto high-capacity DVDs.”
A/V enthusiasts and IT pros takes in a lot of people with a lot of interests. (Say no more : )
But if they’re lucky, both groups may soon get their wish, says an ITplanet.com story here from which we lifted the quote.
“A new standard adopted by the DVD Forum is paving the way for rewritable HD-DVD (High Definition and High Density-DVD) hardware and media that features 20 GB of space on a single side of the familiar 120mm diameter discs,” it says, going on:
“The specification, HD DVD-ROM format version 0.9, primarily developed and pushed by Toshiba and NEC, was agreed upon during the forum’s meeting this week in Tokyo. Though of little concern to storage admins, the read-only version holds up to 15 GB of data.
“The jump in storage space is due to the use of a blue laser that operates at a shorter wavelength (405 nm). This allows burners to pack more of the miniscule ruts that make up the 1’s and 0’s of digital data onto the surface of a disc. Toshiba and NEC pack both red and blue lasers, with a single lens servicing both, for backward compatibility.”
DVD Forum’s approval of the spec gives HD DVD-ROM some momentum, but the battle for next-generation DVD storage is far from over, says ITplanet.com, adding:
“Its biggest challenger is Sony-backed Blu-ray technology, which also relies on blue lasers but is incompatible with HD DVD, enjoys support from industry heavyweights including Dell and HP.”
And of course, there’s Mike Thomas with his 3D Volume Atomic Holographic Removable Optical Storage NanoTechnology.
