How Blu-ray Discs Work A single-layer Blu-ray disc, which is roughly the same size as a DVD, can hold up to 27 GB of data-- that's more than two hours of high-definition video or about 13 hours of standard video. A double-layer Blu-ray disc can store up to 50 GB, enough to hold about 4.5 hours of high-definition video or more than 20 hours of standard video. And there are even plans in the works to develop a disc with twice that amount of storage.

Build Your Skills: A comparison between DVD and CD-ROM As you learned in my All About CD-R and CD-RW Daily Drill Down, CD-ROM data is stored in patterns of pitted and unpitted (“land”) areas on a disc. DVD data is stored the same way, except the pits are much smaller and closer together. That’s why CD-ROMs top out at about 650-700 MB of data, while DVDs can hold multiple gigabytes of data. Since the pits are more tightly written on a DVD disc, the mechanism in the drive for reading them also has to be finer and more precise.

A single-layer disc can hold 25GB. A dual-layer disc can hold 50GB. To ensure that the Blu-ray Disc format is easily extendable (future-proof) it also includes support for multi-layer discs, which should allow the storage capacity to be increased to 100GB-200GB (25GB per layer) in the future simply by adding more layers to the discs.

DVD As a result, the DVD specification provided a storage capacity of 4.7 GB for a single-layered, single-sided disc and 8.5 GB for a dual-layered, single-sided disc. The DVD specification ended up similar to Toshiba and Matsushita's Super Density Disc, except for the dual-layer option (MMCD was single-sided and optionally dual-layer, whereas SD was two half-thickness, single-layer discs which were pressed separately and then glued together to form a double-sided disc) and EFMPlus modulation ...

- At these file sizes, a DVD-R can hold about 2,200 pictures or around 1,100 MP3 files. That’s good for a disc, but it’s pretty mind-boggling when you look at how much more a Blu-ray disc holds. With a 25GB capacity (or 25,600 MB), a Blu-ray disc can hold up to 11.6 hours of DVD quality video. That’s over 9 hours more video on a Blu-ray disc than on a DVD disc at the same level of quality. Of course, most folks use Blu-ray discs for their intended purpose: high definition video.
