Optical disc offers 500GB storage (It's Like a DVD)

A disc that can store 500 gigabytes (GB) of data, equivalent to 100 DVDs, has been unveiled by General Electric.

The micro-holographic disc, which is the same size as existing DVD discs, is aimed at the archive industry.
But the company believes it can eventually be used in the consumer market place and home players.
Blu-ray discs, which are used to store high definition movies and games, can currently hold between 25GB and 50GB.
Micro-holographic discs can store more data than DVDs or Blu-ray because they store information on the disc in three dimensions, rather than just pits on the surface of the disc
The challenge for this area of technology has been to increase the reflectivity of the holograms that are stored on the discs so that players can be used to both read and write to the discs.
Brian Lawrence, who leads GE's Holographic Storage said on the GE Research blog: "Very recently, the team at GE has made dramatic improvements in the materials enabling significant increases in the amount of light that can be reflected by the holograms."

Well even though the market for this kind of Technology might be down with this deep economic recession. I'm happy that technological progress is occurring even in this climate. ^_^

I just wonder if were still going to use plastics for these once fossil fuels run out. XD

Wow, this would totally come in handy as an inexpensive alternative to external HDDs for backing up hard drives.

On a less practical note, this means single disc TV show collections aren't too far ahead. Which is pretty cool. I can see entire runs of TV shows being put on DVD this way, or entire music discographies, all on a single disc.

This is very awesome.
 
wow, they finally came huh? I remember reading about HVD (Holographic video discs) that were supposed to hold up to 3TB of information by bouncing a laser of a holographic film on the underside of the disc, but I think the company that was working on it went bust or stopped working on this idea

I have read that Hitachi had plans for new Hard disks that used a laser to "Heat up" the surface of the drive to store information, but that is planned for near 2015.

I love how technology is advancing like this. Yes I am a geek 0_o

Holy crap, you're right!

That will be awesome.
 
I don't see companies releasing entire-TV-shows-on-one-disc, though. These all-in-one discs would most likely be just as expensive as buying all the boxsets at once, which means we'll be talking about discs that cost hundreds of dollars.

Paying $30 or so once every few months for a set containing, say, 26 episodes is a lot more feasible for a lot of households. But being expected to plop down hundreds of dollars all at once? The majority of people won't have it.

There are a number of other issues as well. Scratching one disc in a boxset and rendering it unplayable is one thing, but what happens when you make an entire TV series unplayable? And what about the people who only want select seasons of a show (i.e. The Simpsons) and wouldn't want to pay the cash for the other, suckier seasons?

I suppose you're right, but it would be good to archive the TV shows I already own onto a single disc.
 
Oh god if they did release TV show series on one disc that would be so much easier!
 
Wow really? And I thought it was hard for an SD card to hold 2TB XD
 
All I can do is wonder how the music industry will react. This is pretty huge.
 
That would be cool, but when it would come out, it would cost lots of money (like blu ray/hd dvd did when they first came out).
 
cool, now video games can have bigger maps, more weapons and characters, and better graphics if they use it.
