Tiny huge 1 terrabyte optical disk
It is called the TeraDisk and it is really small, like a ordinary CD/DVD. But it’s really huge in terms of space. 1 TB (1000 GB). How can this be done? The process is easy (or not). All existing optical media record data on semitransparent layers. A regular CD has 1 layer and a Blu-Ray disk has up to 8. The reason nobody can add more layers on a regular CD/DVD/Blu-Ray disk is because when the light passes through these layers it becomes distorted and by the time it reaches the final layers it becomes almost impossible to read/write on the disk.
TeraDisk achieved the 1TB limit by using 200 layers, each storing 5GB of data. So basically the data support stay the same (TeraDisk will be made out of the same plexiglas like material used in other disks) but the write/read laser technology is completely new. They say it’s going to be cheap and it will be available for the public in 2010.

this disk is to small 4 me
I agree I need at least 2TB for decent HD recording…I only get 130hrs with 1TB…I need more!
WOULD NOT SUFFICE FOR ME. HOW MUCH 4 D PETADISK?
I found this information useless because you did not state how they overcame the refraction issue that is found in blu-ray
There is a link to Mempile’s site in the post. That link would take you to
http://www.mempile.com/The+Chromophore/
http://www.mempile.com/Two-photon+optics/
where you can get your explanation about how this works.
Instead of multiple layers they have one thick layer and just write different info at different depths. It is a 3-D storage medium !
…Awesome.
why just have 1 TB when you can have 3.9 http://en.wikipedia.org/wiki/Holographic_Versatile_Disc
If they use ultraviolet wavelengths of light they can get up to 6-8 PB (peta bytes) on a single 5.25 disk 1 Layer.
It’s terabyte not terrabyte
That’s pretty awesome. It’s amazing how much information we can put into this stuff.
Next Gen gaming format anyone? I’m sure this will be a big hit for companies like Sony and Microsoft. Sometimes technology just blows me away…
that’s hot
Mind blowing technology! I’m impressed.
You do realize 5×200 equals 1000gb , not 1024gb (one terabyte) right?
actually 1000 gigabytes is a terabyte, its 1024 gibibytes in a tebibyte.
You are confusing the SI prefixes of giga and tera with the binary prefixes of gibi and tebi. 1000 gigabytes is 1 terabyte, however 1024 gibibytes is a tebibyte.
Most people don’t understand that kilobyte = 2^10, megabyte = 2^20, gigabyte = 2^30, terabyte = 2 ^ 40, and so on; they’ve taken the approximations (10^3, 10^6, 10^9, 10^12) and assumed those are the “real” gigabyte, terabyte, &c.
Then there’s that entire ‘*bibyte’ nonsense.
Call it a symptom of the AIM era that people are becoming ignorant. Ignore the silly people who don’t know this — double so if you hear them use ‘*bibyte’ seriously in a conversation.
NOW THEY CAN DONE A GTA GAME WITH A MAP OF THE SIZE OF THE ENTIRE PLANET IS GONNA CALL IT
“GTA SAN EARTH”
rofl
It’s not “terrabyte”, it’s “terabyte”.
Were all so impressed by size and speed arent we?
Do you really think it will ever be sold in a 60 pack LOL?
Lets get real, between compata bility issues withe a plathora of different optical read /write, the cost, the time the damn thing will take just to boot up and be recognised by a slow computer, leaves me with the question is it really worth it??? the answer is no, get a real hard drive
Slow computer?
Define slow: Anything with 2Ghz upward and a decent motherboard will be fine with it, provided the FSB is good enough and the method of allocating read-blocks to system memory isn’t insane.
I’ll be honest: I have a 500GB internal and 500GB external setup.
And it’s lightning quick.
A TB is twice that on each end but it’s still no big issue.
Yeah, the only problem is that with one scratch you can wipe out 3 years worth of TV shows.
ftw
This will kill HD-DVD/Blue Ray.
Dead.
It already killed the HD-DVD.
nice disc too bad it won’t be out till 2010 but then again i seen alot of articles for stuff like this i am betting it is going to be vaporware but then again i doubt the disc or the reader will be cheap enough to use like the DVD-Rs of today well lets just wait and see
I’ll believe it when I see it, but I hope they’re successful. Imagine a 1-disk backup of your entire system…
So if we’re able to put a TB on an optical disc, why can’t we have exabyte HDs? Most hard drives on commercial computers at the moment are generally less than or around 500 GB.
Dude where you been..I just bought a single disk external 1TB hard drive that hooks up sata or firewire for $220
yep that’ll kill hd-dvd just like the fmd killed the cd
if you don’t know about fmd
google flourescent multilayer disk
then cry when you read the date on the articles
I hate witnessing this course of this particular technology.
Let me explain…
From CD to DVD to BlueRay to this, and all of above are useless after a tiny scratch. I mean this is the most stupid Hi-Tech concept and is still going.
Furthermore, however this works, the surface that a scratch covers began from destroying some bytes of a CD to megabytes and now?
I agree that the minidisk concept was not the greatest but they still work…
Its already an out of date and old technology. Something better will come along before its released.
This is very interesting, but I personally do not have enough files or use for a 1 terrabyte optical disk hehe. This might be of very good use for large corporations though.
Its not really for file storage but video. Games and movies are starting to even reach the limits of bluray of 50gb.
This smells of bullshit. “Constellation 3D, Inc.” traded under the ticker symbol CDDD on NASDAQ during the internet boom. They claimed to have a 100 layer technology that would store 1TB on a disk, based on some kind of specialized diffraction effect. In other words, almost exactly the scheme I see being peddled here. C-3D never did produce a working unit - as far as I know it was an elaborate shell game. Wikipedia actually has the story here.
I wouldn’t hold your breath
…
This looks like bullshit… where is the citation?
and who the f wrote this? who came up with technology?
stop dreaming
Dude how could it be bullshit if holographic refraction storage techniques have been around for years?? just look at all the wikipedia references in this comment thread alone!
Even if it isn’t a scam, this would be the nth instance of a great-sounding mass storage system, that doesn’t eventuate. Reason being, the producers of consumer electronics have no desire for people to *ever* own a really versatile, high density reliable data storage medium. Because those same corporations are all also invested in ‘content copyright’ - they own the film and music libraries. There is no way they are going to release a technology that threatens their own royalty income stream. So we won’t see TeraDisks on the market, unless ‘they’ can agree on a technical standard that cripples TeraDisk’s potential as a versatile data storage medium, by ensuring the players are all bogged down with DRM disease crap. Pay per view, encrypted file formats, region codings, integration with Microsoft’s ‘trusted computing platform’ (Vista nightmare), etc.
Digital Rights Management - the biggest threat to the further advance of information technology ever. No question. Somehow this bullshit has to be stopped.
lol @ blu-ray.
They need to do solid state memory to that capacity( like pen drives) vs disposable media which as most people said, can be scratched etc.
More Vaporware. Saw back in 2000 some similar statements 1 to 5 TB estimated out in 2005. Yup.
Hi webmaster!
In your face, Mi¢ro$oft!
pretty cool indeed, when will they make the discs smaller though
Now we are getting somewhere, finally i can back up my whole music collection onto just a couple of discs……
wow, this is sweet.
take that, sony. Blu-ray is going down!!
