How to fit 1TB of data on one CD-sized disc
1000GB = 20 times the size of a dual-layer Blu-ray disc

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.

"The TeraDisc is made of a material which is highly responsive to two-photon writing and reading. This allows us to write anywhere in that we can focus a red laser onto the disc, e.g. multiple layers," Dr. Erez told TFOT.info.

"However, many other properties of the material have to be optimised to allow this to work properly. Especially the written points, and written layers have to remain transparent after writing, without which it would be very difficult for the reading process to see the 200th layer through 199 written, non-transparent layers.

"When a red laser is focused to a small spot inside the TeraDisc, we can choose if we probe the state of this material (reading , low power) or alter it (writing at higher power). This is very similar to the way a regular CDR works, except for the fact that this is now done in 3D," she said.

It's hard to imagine that a disc format not invented by one of the world's big technology firms could become a future industry standard. But it's perfectly conceivable that these discs might one day be used in libraries to archive digital copies of books and so forth.

On a 1TB disc, you could store:

212 DVD-quality movies
250,000 MP3 files
1,000,000 large Word documents
 
I've got my entire CD collection ripped onto a 750GB hard drive at full audio size. At 50-100MB per song, space is used pretty fast.

Now, I'm also shooting pictures with a digital SLR and storing uncompressed TIFs at about 100MB each.

Disk space is an issue in my house. Bring on the TeraDisks; that'll make back-up SO much easier.

Mark---I can't even imagine doing lots of film editing. The little bit of raw digital video footage I've put on my computer runs about 500MB per minute of footage.

You would be surprised. Anyone into film editing could easily eat up a few terabytes.

Exactly.

How amazing would it be for a film to be released with its raw footage?

It would be an amateur editor's dream.

Who would honestly need that much space though?

that's a whole lotta porn...

I guess him ^?


But that's asked everytime something like this rolls out. There's always something bigger that will need this much space. I remember a computer teacher saying that no will ever need a Gigabyte of storage......

like you all weren’t thinking that...

:lol: the hard drive on my 386 was 60 mb when I got it and I remember upgrading to 200 mb and thinking it would last me forever...

Get with it people! THIS is the new craze - 100MB on one disk!

:lol: :lol: *still has zip drives* blasted shit things..im in love with my 4GB SD cards tho..:drool:
 
Mmm fair points. And I just read there's like another five levels up of space. The next level is a petabyte I think.

We were told the other day IBM is working on hard drives with single atom storage... imagine that much space for porn.

porn + renewable enegery = the machines take over.
 
Haha, came across this thread on a search & felt I had to bump it just for fun, seeing as how many of us are picking up 1TB external hard drives to back up all of our billions of pictures, movies, music files, etc. I'm actually planning on getting a 2nd 1TB external HD just for my U2 stuff. Crazy.

Please do yourselves a favor and go out and get some real action instead of flooding a 1TB external hard disk full of porn and bragging the fact that you have done it on a forum thread.

Thankies.

Yeah, you pathetic assholes
