Save 9 Times As Much Data On A CD, or 42GB on A DVD
A new breakthrough in DVD technology has made it possible to put 42GB of data on a DVD and increase the amount of data you can store on a CD by 9 times!
Researchers at Tohoku University in Japan have discovered that instead of the more rounded grooves on the standard DVD it has become possible to make the surface grooves more V shaped. That allows for the massive increase in storage capacity.
There is a downside to all this. The new DVD/CD’s won’t work on current players and recorders. This, coupled with the fact that Blu-ray has become industry standard means the new Super-sized DVD’s aren’t likely to make it to market… and no, they can’t apply the process to Blu-ray discs.
The diagram below outlines how this process works.
