HD DVD (short for High Density Digital Versatile Disc)[1] is an obsolete[2][3][4][5] high-density optical disc format for storing data and playback of high-definition video.[6] Supported principally by Toshiba, HD DVD was envisioned to be the successor to the standard DVD format, but lost to Blu-ray, supported by Sony and others.

HD DVD employed a blue laser with a shorter wavelength (with the exception of the 3× DVD and HD REC variants), and it stored about 3.2 times as much data per layer as its predecessor (maximum capacity: 15 GB per layer compared to 4.7 GB per layer on a DVD). The format was commercially released in 2006 and fought a protracted format war with rival Blu-ray. On February 19, 2008, Toshiba abandoned the format,[7] announcing it would no longer manufacture HD DVD players and drives.[6] The HD DVD Promotion Group was dissolved on March 28, 2008.[8]

The HD DVD physical disc specifications (but not the codecs) were used as the basis for the China Blue High-definition Disc (CBHD) formerly called CH-DVD.
