History of optical storage media
High-definition optical disc format war
Super Audio CD (SACD ) is an optical disc format for audio storage introduced in 1999. It was developed jointly by Sony and Philips Electronics and intended to be the successor to the compact disc (CD) format.
The SACD format allows multiple audio channels (i.e., surround sound or multichannel sound). It also provides a higher bit rate and longer playing time than a conventional CD.
An SACD is designed to be played on an SACD player. A hybrid SACD contains a Compact Disc Digital Audio (CDDA) layer and can also be played on a standard CD player.
History<br>[edit]
The Super Audio CD format was introduced in 1999,[1] and is defined by the Scarlet Book standard document. Philips and Crest Digital partnered in May 2002 to develop and install the first SACD hybrid disc production line in the United States, with a production capacity of up to three million discs per year.[2] SACD did not achieve the level of growth that compact discs enjoyed in the 1980s,[3] and was not accepted by the mainstream market.[4][5][6]
By 2007, SACD had failed to make a significant impact in the marketplace; consumers were increasingly downloading low-resolution music files over the internet rather than buying music on physical disc formats.[1] A small and niche market for SACD has remained, serving the audiophile community.[7]
Content<br>[edit]
Many popular artists have released some or all of their back catalog on SACD. Pink Floyd's album The Dark Side of the Moon (1973) sold over 800,000 copies by June 2004 in its SACD Surround Sound edition.[8] The Who's rock opera Tommy (1969), and Roxy Music's Avalon (1982), were released on SACD to take advantage of the format's multi-channel capability. All three albums were remixed in 5.1 surround, and released as hybrid SACDs with a stereo mix on the standard CD layer.
Some popular artists have released new recordings on SACD. Sales figures for Sting's Sacred Love (2003) album reached number one on SACD sales charts in four European countries in June 2004.[8]
Between 2007 and 2008, the rock band Genesis re-released all of their studio albums across three SACD box sets. Each album in these sets contains both new stereo and 5.1 mixes. The original stereo mixes were not included. The US and Canada versions do not use SACD but CD instead.
By August 2009, 443 labels had released one or more SACDs.[9]
