HD DVD (short for High-Definition/Density DVD) is a discontinued high-density optical disc format for storing data and high-definition video.[1] Supported principally by Toshiba, HD DVD was envisioned to be the successor to the standard DVD format. However, in February 2008, after a protracted high definition optical disc format war with rival Blu-ray, Toshiba abandoned the format, announcing it would no longer develop or manufacture HD DVD players or drives.[1] However, the HD DVD physical disk specifications (but not the codecs) are still in use as the basis for the CBHD (China Blue High-Definition Disc) formerly called CH-DVD. The HD DVD Promotion Group was dissolved on March 28, 2008.[2]
Because all variants except 3× DVD and HD REC employed a blue laser with a shorter wavelength, HD DVD could store about 3⅕ times as much data per layer as its predecessor (maximum capacity: 15 GB per layer instead of 4.7 GB per layer).
