高清DVD：酒好也怕巷子深???
????東芝（Toshiba）于2006年發(fā)布高清DVD（HD DVD）技術(shù)標準,，意在取代現(xiàn)有的標準DVD格式,。一張標準的DVD每面僅能存儲4.7GB數(shù)據(jù),，而一張高清DVD的存儲量是前者的3倍以上。不過藍光技術(shù)的市場推廣更有成效,，而且PlayStation 3游戲機也內(nèi)置了藍光驅(qū)動器，藍光技術(shù)最終扭轉(zhuǎn)了競爭局面,。到2007年,，藍光光盤銷售量超過了高清DVD。2008年,，東芝宣布放棄高清 DVD技術(shù),。 |

HD DVD
????Launched in 2006, Toshiba's high-definition density DVD was intended as the successor to the standard DVD disc format. While a standard DVD commonly packs 4.7 GB of information on each side, an HD DVD could store more than triple that. But Blu ray's more effective marketing campaign, and the inclusion of a Blu ray drive on the Playstation 3 console, helped turn the tide in the competition's favor. By 2007, Blu ray discs were outselling HD DVDs, and in 2008, Toshiba killed the format. |
