This article is about comparative HD optical disc formats. For a history of the Blu-ray/HD DVD format war, see High definition optical disc format war.

This article compares the technical specifications of HD DVD and Blu-ray Disc, two mutually incompatible, high definition optical disc formats that, beginning in 2006, attempted to improve upon and eventually replace the DVD standard. The two formats remained in a format war until February 19, 2008 when Toshiba, HD DVD's creator, announced plans to cease development, manufacturing and marketing of HD DVD players and recorders.[1]

There are other high-definition optical disc formats including the multi-layered red-laser Versatile Multilayer Disc and a Chinese variant of HD DVD known as CH-DVD.
