New 500 gig disk


Recommended Posts

"A Japanese electronics giant has developed an optical disk with a storage capacity of up to 510 gigabytes - or just more than half a terabyte.

With its huge storage capacity, Pioneer's 12cm thick (i think this is a typo) silver platter will store the amount of data that would require 100 typical DVDs today. An ultraviolet laser will be used to write to the disk.

In order to attain such storage capacity, scientists had to develop a new laser technology, which emits shorter wavelengths raised than blue lasers, the type used today for the highest-capacity optical disks.

The new ultraviolet laser beam allows "data holes," which are used to store data on optical disks, to be separated by only 70 nanometres, about 20 times better than with blue lasers.

While such a high storage capacity sounds impressive today, it may leave users still wanting more when they find out that such a disk can only hold about 3.5 hours of high-definition television programming.

It is not yet clear when the new high-capacity disks, or the technology necessary to write to them, will be in stores."

...they'll probably use them for the next-generation consoles

Not PS3 or Xbox 2, they say they're gonna use HD-Disks for Xbox and Blue Ray for PS3.

How can 510meg only hold 3.5 hours of High Definition video?

Exactly :huh:

Still cool though. I wonder how long it takes to fill one of those :p

Because HD-video 1920x1080i compressed in MPEG4 takes about 100 mb per minute, MPEG2 even more of that...

I have a bunch of moves and music videos recorded from HDTV and they take alot of space :blink:

I can put my whole data from hard drives into 1 single disk :)

yeah but wouldnt ya just hate to loose that disc :cry:

although id love a 500gb optical disc :woot:

So this already makes blu-ray and hd-dvd obsolete, lets even scrap this idea because in less than 2 months i'm sure we'll have gamma-ray discs with even shorter wavelength.

wasn't there some disc that was capable of more of this?

found the link

"Holographic recording technology records data on discs in the form of laser interference fringes, enabling existing discs the same size as today's DVDs to store as much as one terabyte of data (200 times the capacity of a single layer DVD), with a transfer speed of one gigabyte per second (40 times the speed of DVD). This approach is rapidly gaining attention as a high-capacity, high-speed data storage technology for the age of broadband."

Plus holographic discs sounds cooler don't you think?
