[TheTechDon] Teradisk by 2010

post #1 of 14
Thread Starter 
Talks about new technologoy for terabyte disks. Who needs blueray anymore?

Quote:
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.

Wow so its a 200 layer DVD? Sounds cool but it would probably take a week just to burn 100GB and the disks will probably cost $100 each...

We've already GOT TeraDisks... Yeah, yeah, I know, I know that's not what I they meant... But we DO, technically.

I'll wait until they have something besides drawings and crude pictures.

Umm, wouldn't this affect speed? Like it would make the disc really slow?

Back on topic though, wouldn't having 200 layers make the disc very fragile when it comes to scratches?

Not only that, but couldn't they easily take Bluray (or any high capacity disc storage solution) technology and apply the same kind of idea as they have here? Theoretically, if this was possible with bluray you'd be able to achieve ~5000GB on one disc (25*200).

Let's assume someone somewhere has ~5000GB worth of material(uncompressed video?) and they have both a blank ~5000GB disc and compatible burner... They would most likely spend (@ 2x to burn to a 25GB single layer Blu ray disc = 45mins) 45mins x 200 = 6.25 days to burn a disc... It'd be my luck I get a coaster @ 6 days 5 hours 59 mins time, 1 min before completion.

I wouldnt worry about scratches. The outer layer of plastic just has microscopic grooves that route the lazer around the disk anyway, no actual information is on the outside. I am sure this way will still have the *foil* on the inside nice and safe.
Thats good thinking but remember what they said. The laser setup is all new too. That is why they dont have 200 layer disks/DVD's/BluRay's now. None of the laser technology we use can go that deep without getting very distorted.

I do wonder what type of diode they would use to go 200 layers deep
