Holographic Versatile Disc(HVD) is an advanced optical disc technology still in the research stage which would greatly increase storage over Blu-ray and HD-DVD [high-definition digital versatile disc] optical disc systems. It employs a technique known as collinear holography, whereby two lasers, one red and one blue-green, are collimated in a single beam. These disks have the capacity to hold up to 3. 9 terabytes(TB) of information, which is approximately eighty times the capacity of Blu-ray Disc.

[...] le HVD (holographic versatile disc, disque holographique polyvalent) n'a en fait rien à voir avec ses prédécesseurs optiques que sont CD, DVD et Disque Blu-ray.Contrairement à ces derniers, qui sont une succession de creux lus par un laser, le HVD est en fait un hologramme de 12 centimètres avec une capacité de 3,9 téraoctets (capacité nominale du double). Le HVD est cependant toujours lu par un laser. Il s'agit d'un laser vert, ce qui permet d'envisager un hypothétique «HVD-bluray» balayé par un laser bleu et d'une capacité encore plus grande.
