As Warner Brothers will publish its high-definition DVDs exclusively on Blu-ray it will be hard for the HD DVD format to argue for its high-definition DVD solution.
On the HD DVD side we have Paramount Pictures and Universal Pictures as well as DreamWorks Animation.
Sony’s Blu-ray now has Walt Disney, 20th Century Fox, MGM, Lionsgate and Warner in it’s team.
HD DVD-R and HD DVD-RW have a single-layer capacity of 15 GB, a dual-layer capacity of 30 GB and HD DVD-RAM has a single-layer capacity of 20 GB.
A single layer Blu-ray Disc can store 25 GB and a dual layer Blu-ray Disc up to 50 GB.
Both formats, HD DVD and Blu-ray, are using a ‘blue’ laser at a wavelength of 405 nm to read and write data.
