What are holographic discs?

holographic discs are optical storage devices similar to standard DVDs that can store a huge amount of information. The aim of many companies in this industry is to produce discs that can store up to one terabyte of information. The process includes data recording in the form of three -dimensional patterns on discs that are made of materials with highly reflective indices. Lasers are used to read data from a disk that acts as a mirror. The difference between holographic discs and DVDs and Blu-ray discs is that the information is recorded on the whole disk in layers, leading to a very high information density. It is still evolving technology, and while many companies are in the field, holographic discs have not yet been commercially released at the time of this writing. One prominent company was able to prove 500 GB of information on one holographic disk. From a practical point of view, this means that a disk of this type can store data contained on approximately 100 DVD or 20 single -layer BLu-ray discs. Double storage capacity at rapid speed transfer is the Holy Grail of many holographic storage developers.

Entreneurs are developing the system to be backward compatible, so holographic disc players can also read CDs, Blu-ray discs and DVDs. When the technology matures, the only holographic disc with one tertiac capacity could theoretically save the entire collection of high -definition movies. Its developers, which are sold as an economic alternative to current storage technology, hope that holographic discs appear as a reliable form of backup production. The initial costs are expected to be quite huge when disks players cost $ 20,000 in the US (USD) and one disk costs $ 50 per USD USD. Many believe that a significant number of competition and mass production will run the price of holographic discs over time.

holographic discs and players areInitially focused on the archiving industry, where data must be stored in the long term. Film studios and medical offices must store data in an indestructible format, but it is extremely demanding for current technologies that have a limited life. The process of storing information in the form of holograms on the disk and in each layer of disk is a very robust data storage solution. In the end, developers hope to create available new generation holographic discs and players that the average consumer can use.
