Whois & Analysis for deepdiscount.com

Blu-ray or Blu-ray Disc (BD) is a digital optical disc data storage format.

It was designed to supersede the DVD format, in that it is capable of storing high-definition (720p and 1080p) and ultra high-definition video resolution (2160p).

The plastic disc is 120 mm in diameter and 1.2 mm thick, the same size as DVDs and CDs.

Conventional (pre-BD-XL) Blu-ray Disc discs contain 25 GB per layer, with dual layer discs (50 GB) being the industry standard for feature-length video discs.

Triple-layer discs (100 GB) and quadruple layers (128 GB) are available for BD-XL re-writer drives.

The name "Blu-ray" refers to the blue laser (specifically, a violet laser) used to read the disc, which allows information to be stored at a greater density than is possible with the longer-wavelength red laser used for DVDs.

The main application of Blu-ray is as a medium for video material such as feature films and physical distribution of video games for the PlayStation 3, PlayStation 4, and Xbox One.

Besides the hardware specifications, Blu-ray is associated with a set of multimedia formats.

DVD (an abbreviation of "digital versatile disc" or "digital video disc") is a digital optical disc storage format invented and developed by Philips, Sony, Toshiba, and Panasonic in 1995.

The medium can store any kind of digital data and is widely used for software and other computer files as well as video programs watched using DVD players.

DVDs offer higher storage capacity than compact discs while having the same dimensions.

Compact disc (CD) is a digital optical disc data storage format released in 1982 and co-developed by Philips and Sony.

The format was originally developed to store and play only sound recordings but was later adapted for storage of data (CD-ROM).

Several other formats were further derived from these, including write-once audio and data storage (CD-R), rewritable media (CD-RW), Video Compact Disc (VCD), Super Video Compact Disc (SVCD), Photo CD, PictureCD, CD-i, and Enhanced Music CD.

The first commercially available Audio CD player, the Sony CDP-101, was released October 1982 in Japan.

A gramophone record (phonograph record in the US), commonly known as a vinyl record or simply vinyl or record, is an analog sound storage medium in the form of a flat polyvinyl chloride (previously shellac) disc with an inscribed, modulated spiral groove.

The groove usually starts near the periphery and ends near the center of the disc.
