4.7 GB DVD disc's...when do you think they will release 6 or

[VEBouto]

8 or even 10 GB blank DVD disc's. If the manufacturers do release them then won't the dual layer medium become useless?
Can you see larger capacity blank disc's coming any time soon?

an 8gb disc would have to be dual layer... 4.7 is the max for a single layer disc.

DVD players were made from day one to support dual layer DVD discs ... it just took a while for them to actually figure out a good way of making dual layer DVD discs but I guess they knew enough ahead of time that they did make sure players could handle it.

As far as I know there was was no foresight in ever doing more than a dual layer DVD disc.

In short I don't think DVD players would work with a DVD disc that had more than 2 layers unless they change DVD players but that wouuld mean that any 3 or more layered DVD disc would only work on the new DVD players that support them.

Chances of that happening is nil if you ask me especially since they are pushing foreward with totally new formats like HD-DVD or blue-ray etc.

Wasn't there actually a company which released discs with a bit more space? I don't recall how much, it might have been an extra 80MB or 300MB or any other number.

Maybe you're thinking of the supposed 100MB difference between DVD-R and DVD+R, with DVD-R supposedly having a bit more?

For all practical purposes 80 or 100MB doesn't make much difference in bitrate calculations and resulting quality.

There was a version 1 of DVD-R which was 3.9GB. But those aren't around except in special cases and then only the authoring type which require a different wavelength laser that a standard PC DVD writer.

What about double sided dual layer. Those are supposed to hold 18 gigs. Seems like that would be the next step maybe by end of next year.

This kind of DVD already exists as a commercial factory made disc ... but not as a recordable.

P.S.
The NTSC USA DVD of Stephen King's mini-series THE STAND is like that.

DVD-18. Windwalkers is another one.
