In order for a disc to be classified a holographic type optical drive there needs to be a holographic data layer in the disc. There is no such thing in a blu-ray disc, all there is are 1 or 2, maybe even 4, 8 or 16 soon enough, metallic layers in them. That is were the information is stored, unlike holographic media which has one metallic layer for positioning and a holographic data layer for information storage.
