Dual layer does not write on both sides of the disc. Dual layer is just
that, dual-layer on one side. There are two data layers and the laser is
basically refocused depending on which layer needs to be written or read.

The dual layer drive writes on two sides of a cd. You have to purchase
these cds as you can not write on the cds that we are currently using.
My experience has been that so far the DL is not totally reliable when
The Phillips that comes in the Dell computers are a nightmare.
Unless you are going to write with DL cds and do extensive dvd
authoring I would get a writer that is more reliable and wait till
they perfect these more.
Dual layer drives have double the capacity
