What is Blu-ray? No, it’s not a creature of the deep or any legendary beast. Blu-ray is a third-generation digital media or information storage space innovation from the Blu-ray Disc Association, an assembly of company media and electronic devices innovation leaders. Blu-ray discs are currently taking on HD-DVD to become the brand-new optical disc format. They have a lot more storage abilities and information transfer speeds than conventional DVD’s as well as CD’s.

Blu-ray Disc Versus Various Other Optical Discs

A Blu-ray disc, looks similar to any other optical disk, including first-generation CDs, second-generation DVDs, and the competing third-generation HD DVDs.

A Blu-ray disc system uses a blue-violet laser with a wavelength of 405 nanometers to compose and also read information on the optical disc. This laser is the source of Blu-ray’s name and the innovation which distinguishes Blu-ray from previous generation optical media. The 405 nanometer blue-violet laser is additionally utilized for creating and reading data on third-generation HD DVD discs, which have smaller information storage space capacity per layer. Older optical media require a red laser for data storage as well as retrieval.

Blu-ray Storage Ability

The Blu-ray disc system utilizes a shorter wavelength than conventional optical discs (CD systems utilize a red laser with a wavelength of 780 nanometers whereas DVD systems make use of the exact same red laser with a wavelength of 650 nanometers). The much shorter wavelength suggests a lot more specific data recording, which permits extra information to be loaded on the Blu-ray disc surface than a similar CD or DVD surface area. In fact, a standard single-layer Blu-ray disc can store as high as 25 GB of electronic information, greater than 5 times the storage capability of traditional DVDs. A dual-layer Blu-ray disc can store a maximum of 50 GB of electronic information. On the drawing board are quadruple-layer Blu-ray discs with 100 GB digital information storage capacities.

Blu-ray Assistance

To enjoy the considerable benefits of a Blu-ray disc, one have to have a Blu-ray disc player (either standalone or software-based) that sustains analysis of the Blu-ray disc. Blu-ray video players need to have an MPEG-2 codec (which makes a player with the ability of playing DVDs as well as HD DVDs), a VC-1 codec, and an AVC or MPEG-4 codec. Motion pictures stored in Blu-ray discs will make use of any type of one of the above-mentioned codecs. One movie can likewise have greater than one codec, as long as each codec used is sustained by Blu-ray modern technology.
