HD+DVD

=__﻿HD DVD History__= This type of dvd is not as widely used as blu ray as when they where both new there was a massive 'Format war' this is where the two main discs (HD DVD and Blu ray discs) went head to head in an all out war against each other to see which would be the dominant disc, from this battle blu ray emerged victorious as is more widley used. one of the main reasons for this is that a number of companys who made games consoles mainly sony and nintendo backed the blu ray disc instead of the HD DVD which was only backed by microsoft then the HD DVD failed to beat the blu ray and then it became less popular than the blu ray and also less bought.

All DVD's can either be single or double layered this will increase the amount of space that each disk can hold and if a HD DVD is single layered then it can hold 15GB and if its double layered it can hoild 30GB this is a lot less than the blu ray and this was one of the reasons it failed. Even though blu ray and HD DVD are two very different formats they are both made by a laser burning into the material to create space for memory on the DVD. The HD DVD uses1080p high definition video and is also an add-on to the xbox 360.
