The burning software that comes with the drive is Nero Express, which makes us wonder why the full version of Nero Burning ROM wasn't bundled in....

The Gigabyte GO-W1616A is not compatible with DVD-RAM discs or Mount Rainier , but supports all other DVD and CD-R/RW formats listed above.

Dual-Layer DVD Technology

Dual-layer DVD media can store 8.4GB of data, which is exactly twice that of its single-layer counterparts capacity of 4.7GB. This is because DL DVD media has two dye layers for data recording. Heat caused by the drive's laser beam modifies the physical and chemical structure of each dye layer to form patterns which can be read by the same laser (at a lower intensity) as digital data.

Each dye layer is separated by a spacer and a metal reflector. The metal layer reflects the laser light, allowing the drive to 'read' the data by observing the reflections. The first reflector (positioned after the first dye layer) is semi-transparent; when the laser is focused a certain way, it will pass through this reflector and continue through to the second dye layer and bounce off the second metal reflector. This allows the drive to read the second layer of data. The second reflector is completely opaque and will not allow the laser beam to pass any further. Thus, by modulating the frequency of its laser beam, a dual-layer capable DVD-writer can read and write to dual-layer DVD discs.

There are a couple of ways to indicate dual-layer media. The most common is 'DVD+R DL' but it's also sometimes indicated as DVD+R9. Obviously, both the drive and the media need to be dual-layer capable in order to access the extra storage space afforded by these 8.4GB monster optical discs!
