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.
Frequently Asked Questions. Dual layer and double layer DVDs are the same thing and are also referred to as DVD-9 discs and have a capacity of 8.5GB. In dual layer DVD-9 discs, two layers of standard DVD-5 are joined together with a transparent spacer and a thin reflector between the two.
That is accounted for the lower capacity of a single-sided dual-layer DVD at 8.5 billion bytes, versus a double-sized single-layer DVD at 9.4 billion (for 12 cm discs).
The DVD+RW camp, which includes Hewlett-Packard, Dell and Philips, plans to put so-called "double-layer" DVD recording devices on the market by next spring. Discs on these systems are expected to hold 8.5GB, or four hours of DVD-quality video (16 hours of VHS-quality video). That's about the same amount as the DVDs studios use to issue movies.
Blu-ray Disc Recordable (BD-R) refers to two direct to disc optical disc recording technologies that can be recorded on to a Blu-ray-based optical disc with an optical disc recorder. BD-R discs can be written to once, whereas Blu-ray Disc Recordable Erasable (BD-RE) can be erased and re-recorded multiple times.
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.
In trying to make the most of the space, you'll have some DVDs stacked vertically, some horizontally, some just squeezed in wherever they'll go. The Billys are also at least two DVDs deep so I've ended up double stacking mine.
The Blu-ray Disc® player is capable of playing back the DVD side of Dual Disc. However, playback of the CD side of a Dual Disc is not guaranteed.

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.
Discs are best stored upright (like a book) in "jewel" cases that are designed specifically for CDs/DVDs. Ideally, store the cases in plastic or steel containers manufactured specifically for the type of medium in cool, dry storage that is free of large temperature fluctuations.
The disc should be stored in its case and placed vertically, like a book, on a shelf. Long-term horizontal storage, particularly in a heated environment, can cause the disc to become permanently bowed.

When you place a DVD into a Blu-ray Disc player, it activates the red laser assembly so that the DVD can be read. When you place a CD into a Blu-ray Disc player, the same red laser assembly used for DVDs is refocused to read the CD.
There are several reasons a disc may not play in the Blu-ray player. A dirty or scratched disc is the most obvious cause, but an incorrect region code or configuration of your home theater system can be the reason as well. Whether you're having trouble with 4K or 3D, Blu-ray or DVD, there is a fix.
All types of Blu-ray players can also play standard DVDs and CDs, so you can use one player for all your discs. Some models may support other types of specialized discs, such as audiophile Super Audio CDs (SACDs).
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.
There are several recordable DL DVD formats, but you’re only likely to come across two in the shops at present. As of mid-2008, the vast majority of discs on sale are DVD+R DL, with a smattering of its rival, DVD-R DL. Both are write-once (i.e. they can’t be re-recorded).
There are other types of recordable dual layer DVD, but they’re all rare and/or poorly-supported at present. You’re unlikely to come across them in the shops.
