*sigh* HD-DVD uses a blue laser as well. And currently on the market HD-DVD stands at 30 GB dual layer and Blu-Ray at 25 GB single layered.Timepass said:HD still uses a red lazer which limits puts phycal limitation on data density that can not be broken.
HD-DVD has hopes for a triple layered 45 GB disc for future expansion.
And finally I supported -R and the DVD forum the last time around.
