Tweet

Here it comes the future technology in storage media, Holographic Versatile Disc or HVD is an optical disc which can hold up to 3.9 terabytes(TB) of data. HVD uses collinear holography technology, whereby two lasers (one red and one blue-green), collimated in a single beam. Blue to read the top layer, and red to read the bottom layer. HVD have the capacity to hold up to 3.9 terabytes (TB) data, approximately 6,000 times the capacity of a CD-ROM (600 MB), 830 times the capacity of a DVD (4.7 GB), 160 times the capacity of single-layer Blu-ray Discs (25 GB), The HVD's transfer rate is 1 gigabit/s. It takes more than one year of uninterrupted video at usual encoding rates played. Lets see more what the future brings.
