DVD 9 question (no, not a "how do i burn a dvd 9 to dv

[Dkreaky]

question.. theoretically..

if DVD 9's were abailable for purchase would that require a new type of DVD burner? or the standard ones that are out now can write to a DVD 9?

It would require a burner that is imposible to make.

DVD Burners work by heating up the aluminum substitute in the plastic to very high degrees to melt it, leaving a little "pit". A series of the pits makes up the information. DVD9 is dual layer, that means it has one translucent layer, so that the read laser can read through to the next layer. To burn this you would have to melt the material on the other side of the translucent layer. How would you do this with out as well melting the layer before it? It really is impossible.

It could be done. but would require a lot of work.

DVD9 (daul layer) discs are made by pressing to single layers together. Remember that commerical DVDs are not burnt, they are pressed (from a glass master). There's no way to burn a DVD9.

With the introduction of Blu-ray (do a forum and/or google search) it's even more doubtful that anyone would even attempt to research this.

Yep. People will just make more densely packed single-layer burnables.

I have heard of having even more than two layers on optical mediums (3 and 4), I wonder why they did incorporate this into blu-ray. The amount of data would be incredibly high, it would barley fit on a standard hard drive, the quality would be incredible cause you could fit uncompressed video on it, and would decrease piracy considerably due to the inconvenience.
But then again, it is a bit more expensive to produce the disks that way.
