Difference between Dual-Layer and double-sided DVD
Dual-Layer DVD
Dual-layer DVDs were first introduced in the year 2004. It is basically a disc with two recordable dye layers each capable of storing nearly 4.7GB of data. So, the total capacity of these types of DVDs is 8.5GB as there are two recordable dye layers, although it has only one side. In this type of DVD, you will be able to store nearly 4 hours of video.
These types of DVDs are compatible with most of the devices, although you may sometimes face a few issues in some of the older devices. While using Dual-layer DVDs, you will come across two different formats, including DVD-R Dual Layer, and DVD+R Dual-layer format.
Moreover, there are two modes for dual-layer orientation: parallel track path (PTP), and opposite track path (OTP). In PTP mode, both layers start recording at the inside diameter (ID) and end at the outside diameter (OD). On the other hand, in OTP mode, the lower layer starts at the inside diameter (ID) and the upper layer starts at the outside diameter (OD) where the first layer ends.
A dual-layer DVD can store up to 8GB of data, which translates to about 4 hours of DVD-quality video. This is nearly double the capacity of a standard single-layer DVD.
