Dual layer DVD discs are 12cm in diameter and can have the content data added through the production processes of either DVD duplication or DVD replication.
DVD±R dual-layer discs adopt 2 recordable dye layers with each capable of saving about 4.7 GB of data of a single-layer (SL) disc, almost doubling the total disc capacity to 8.5 GB. They can be read on many DVD devices with less compatibility with older ones. What is double layer DVD?
DVDs have much higher storage capacities than CDs by using smaller pit sizes and narrower track pitches in the spiral groove that runs around the discs. These smaller pits and grooves require a different wavelength of laser light (650nm) to that used in CD drives (780nm) and therefore DVD discs cannot be read in standard CD drives.
The writable versions of DVD-9 discs that can be bought in the shops are often referred to as DVD-R DL, with the DL referring to ‘Dual Layer’.
DVD+R DL discs employ two recordable dye layers, each capable of storing nearly the 4.7 GB capacity of a single-layer disc, almost doubling the total disc capacity to 8.5 GB.
Normally if you look carefully at all the symbols on the face plate of the drive you will see on the DVD Multi icon. At the bottom of that, you should see a little R DL. That means it will write Dual Layer.
Dual layer disks are still regarded as less reliable than single layer, even the Verbatim disks.
Classic anime with a lot of film grain has a harder time with the bitrate limitations of streaming video, and in that case the difference can be much more noticeable. Blu-ray also supports much better (lossless) audio and full graphical subtitle options, which most streaming services simply can't touch.
Yes. Dual layer media plays just fine in standard DVD players.
You do. The drive has to be able to realign the write optics to focus on the second layer. Most modern DVD writers support dual-layer, but older ones might not.
A DVD is a standard definition device. You won't get high-definition movie viewing on your DVD, just 480 SD. On the other hand, Blu-Ray is made for HD, and you'll get the best picture possible, with 1080 HD capability for your Blu-Ray movies. So if you are looking for a quality picture, Blue Ray is the clear winner.
Conventional or pre-BD-XL Blu-ray Discs contain 25 GB per layer, with dual-layer discs (50 GB) being the industry standard for feature-length video discs.
What is the difference between 16x and 8x? 16 and 8 are the write times for each particular disc. Theoretically, a 16x disc will write at twice the speed as the 8x disc. Discs are backwards compatible, as long as you are using a burner that can support the higher write speeds.

Of course, the home releases of anime programs often look better than the broadcast versions. Anime studios have more time to tweak their art, and they can also make some extra scratch on the Blu-ray. Previously, Kotaku showed comparisons between the disc releases and the TV originals.
Because of BD's technology and greater storage capacity, it can hold not only high-definition video, but high-definition audio and lossless audio. These capabilities allow BD to hold a much richer array of special features, especially interactive features and graphics that DVDs can't possibly handle.
To learn the meaning of a dual-layer (DL) DVD, let’s look at the definition of the DVD+R DL and DVD-R DL.
Dual-layer recording enables DVD+R and DVD-R to save significantly more data, up to 8.5GB per disc, compared with 4.7 gigabytes for single-layer discs. Double-layer DVD-R was designed by Pioneer Corporation for the DVD Forum, whereas dual-layer DVD+R was created by Philips and Mitsubishi Kagaku Media (MKM) for the DVD+RW Alliance.
There are 2 kinds of dual-layer orientation, opposite track path (OTP) and parallel track path (PTP).
The following is a table showing the storage capacities of the 4 most common DVD recordable media, excluding DVD-RAM.
