TeraDisc Promises 1TB+ Optical Media

Blu-ray and HD DVD have pushed the limits of optical storage further than anyone thought possible. But a new technology has emerged which makes Blu-ray's 50GB capacity look tiny. Mempile in Israel says it's able to fit an incredible 1TB of data onto one "TeraDisc" which is the same size as CDs and DVDs. That's 20 times the capacity of a maxed-out dual-layer Blu-ray disc.

The incredible capacity achieved using this new technology is made possible by employing 200 5GB layers, each one only five microns apart. The discs are completely transparent to the red lasers which are used in the associated recorder. Prototypes have already been made to store up to 800GB of data, and Mempile says it will crack the 1TB barrier before moving on to build 5TB blue laser disks. Dr. Beth Erez, Mempile's Chief Marketing Officer says that the first 1TB disks have a lifespan of 50 years and could be on the shelves in two to three years.

How much PORN do you people have, that you need 100gb and 500gb DVD's?!? My goodness!

Over 80gb and counting. And that's after a massive loss of data, due to me and a copy of partition magic. :'(

Yeah, until someone shows a public demonstration of a working disk, I will continue to call it vaporware.

Pretty much what I was thinking. How many other companies have claimed to put layers upon layers? This is more suited to server and company use anyway.

This is WAY more than enough. Most consumer drives don't even touch 1TB. This is something more useful for server backup I suppose, but even then they use other methods.

Maybe when demand requires 1 TB this might hold some popularity in the consumer market.
I personally, can't seem to fill even 40 GB of my 160 GB drive.

I think you'll find that many consumer drives do get that high, and that the volume you require would depend on the usage.
Personally I have used over 500 GB.

People should read the links they post (ahem psykx ).

Optware was expected to release a 200 GB disc in early June 2006, and Maxell in September 2006 with a capacity of 300 GB and transfer rate of 20 MB/s.[2] Since the announcement, there have been no further news or products on market.

No, it just proves that incredible technologies like that never create a gap in terms of advancement.

A 200GB disc didn't come out in 2006, and I highly doubt that a 1 TB or a 5 TB portable media disc hits the shelves in 2008, 2009 or even 2010.

It's good to see that there are known ways to make it though.

We could easily jump to those 1-5TB disks, but do you imagine how much money would companies loose because of going so fast to the future? We will be living long years with BD and HD-DVD. But as I thinking more, it looks like 50GB isn't enough and 100GB is a bit low too...

The better the technology is the more money they'll make, and even if it quickly dwarfs their last offering, they'll still be stinking rich anyway.

Yeah, it beats a dual layer blu-ray, but so what? A quad-layer blu-ray can hold 100 GB. I'm sure if they wanted to spend the time and money they could make a 20- to 40-layer disc, and with 25GB per layer...

They really can't because of the problems with the beam penetrating the layers and the focus of the beam. Not to mention such disks are a long way away because of current production.

Whereas this is gonna hit us in the next 2-3 years. Good stuff.

The jump from 1.4MB floppy discs to 650MB CD's is more than X450.
Jumping from 4.7 (Or 9 DL) DVDs to 50 isn't enough in my opinion.
This is enough :nuts:

I hope they'll get more money and boost it quickly to 5TB.
