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.
