What is a dual-layer disc, and what are the benefits?
One of the great benefits that DVD offers is its ability to store information on both sides of the disc and in two layers on each side of the disc. Although no one has been able to practically create a dual-layer, dual-sided disc yet, many studios have used single-sided dual-layer discs for movies that won’t fit on one side of a single-layer DVD. The movie is stored on two layers sandwiched on one side of the disc, both of which your DVD player reads seamlessly. This way, you don’t have to flip the disc over to continue watching the movie. For movies that aren’t too long to fit on one side of a disc, some studios have chosen to put the pan & scan and letterbox versions on two layers on one side. On these discs, as soon as you put the DVD in the player, it will ask you which format you want to see the movie in, then read that layer.
The main benefit of a DVD is that it can store information on both sides of the disc and in two layers on each side of the disc. Many recording companies already use single-sided dual-layer discs for movies that can’t be fully recorded on one side of a single-layer DVD. The movie is stored on two layers sandwiched on one side of the disc, both of which the DVD player can read seamlessly. This way, you don’t have to flip the disc over to continue watching the movie.
