Re: Dvd +/- Dvd 9?
Dual layer burns on two different layer of ink (I believe). It allows the DVD to have twice the capacity of the other (single layer) DVDs. The "9" refers to the number of GB it can store.
I'm guessing there are either two lasers - one focused on each layer or one laser which focuses on the particular layer that it happens burning.
