Are there rewritable dual layer DVD's?

Hi,everyone.Just a simple question:
Are there rewritable dual layer DVD’s?
I know that the simple DL DVD’s can be bought at fair prices nowadays,but I was wondering about that.
Thank you in advance.

There have been some work done specifying and developing Dual/Double Layer Re-writable DVD media, but the media never really entered the market and probably never will, since it wouldn’t be compatible with existing DVD readers/players.

Exactly. JVC & MKM (and maybe other companies too) have a working samples of DVDRW DL media, but they will be probably never released on the market.

Thanks for the answers,everyone.
