Sexy Tiny 1 Terabytes Disc?

I know this may sound ridiculous to many of you. How come there is 1 terabytes Sexy Disc in the market?Well it may not that sexy actually it is just tiny 1 Tera bytes disc available for sale on 2010. This disc is the same like the normal ordinary disc you can found in the computer shop and maybe at your Cd case. The difference? well you can fill up 1000GB data in it.

The question: Is this possible? or just a myth? Hahah i know some of you already knew about blue ray! and if am not mistaken that is the largest Disc space ever available to the user. So is this possible and how they are going to do it?

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.
