A typical single-layer DVD, when written to it with default settings, holds less than 4.38 GB of usable data. This recording format is referred to as DVD-5, and besides it there is also the DVD-9 format. Such discs allow recording twice as much data as they have two magnetic layers. Most modern optical disc burning software is designed to work with both single layer and dual layer DVDs.
Necessary
Double layer DVD + R disc, computer with DVD burner, Nero Burning ROM application
Instructions
Step 1
Check that your software is ready for recording a dual layer optical disc and replace it with a more suitable one if necessary. If you have any application installed on your computer that was last updated in working code about five years ago, it is better to replace it with a more modern one. Most programs for recording discs of that period had problems with determining the place of transition of the original recording from one layer to another (layer break marks), which led to temporary or permanent distortion of the image during playback.
Step 2
Look for a disc labeled DVD + R if you have to record or play a disc on a non-new DVD drive. Many readers are designed to work only with a predefined list of DVD types. If the marking of the blank you are using is not included in it, then such a drive will not even try to reproduce it. The code (bitsetting), by which the membership in the list is determined, is recorded in the service area of the disc (lead-in) and cannot be changed for DVD-R discs, and any value can be placed there in DVD + R - for example, zero, which will surely be on the DVD drive's "white list".
Step 3
Once these two prerequisites are met, recording a dual layer disc will be very little different from a normal disc. For example, if you are using the Nero Express version of the popular Nero Burning ROM media suite, insert the disc into the burner, then select the type of disc you want to create in the left column of the Nero Express interface (Data, Music or Videos / Pictures).
Step 4
In the next form, find the drop-down list above the "Back" button and select the line DVD9 in it. Only after that start creating a list of files for the disc to be burned - click the "Add" button and select the desired group of objects (files or folders). The degree of fullness of a two-layer disc can be monitored by a color indicator - it will change color first to yellow and then to red.
Step 5
Click the Next button and enter a title in the Disc Name field. If later you plan to make changes to the composition of the files on this DVD, check the "Allow adding files (multisession)" checkbox.
Step 6
Click the "Burn" button and the process of burning a two-layer disc starts. You will see information about its progress in the corresponding window on the screen.
