Blu-ray Disc®

(Redirected From BD)

From Wikipedia, Chace Audio

Blu-ray Disc® (BD) is a high-density optical disc storage format developed by Blu-ray Disc Association in the early 2000s. The name Blu-ray comes from the use of a blue laser to read and write the discs. Due to its shorter wavelength, the blue laser allows more data to be stored per disc than the red laser of previous optical disc formats. It can hold up to 25GB on a single layer and 50GB on a dual layer disc. The primary uses for Blu-ray Discs are storage of data and high-definition video/audio.

Blu-ray Disc was embroiled in a bitter format war with Toshiba's similar HD-DVD format in the 2000s, but by the end of the decade, Blu-Ray emerged victorious as the standard physical high definition home entertainment format.
