Storing big data is not an easy way but is never impossible with the help of holographic data storage. It is also called as the 3D storage. This technology involves the storage of data by making holographic images of every data instantly on a bolstered medium.
This depends on the idea of optical storage gadgets though it empowers the utilization of a single storage volume to store a lot of information. It records the information throughout the volume present in the medium. Moreover, it is capable of recording multiple images in the same area by using light and different angles that are available. Anyhow this holographic storage is split into two: one is write-once that is irreversible and the other is rewriteable media. Rewriteable holographic can be achieved by photorefractive impact in crystals.
Now if we look at the framework then it consists of a blue-green argon laser, beam splitters, reflectors, an LCD board, lenses, lithium-niobite crystal, and a charge-coupled device camera. So now the blue-green argon laser would be discharged and then with some assistance from the beam splitter, the laser shaft would be a part into two beams. One of these beams called the signal beam. This beam would rebound off a mirror and then travel through an LCD display to the lithium niobite crystal & the other beam known as the reference beam would approach in an alternative way. But the point is that when these two beams meet the information put in is put in a hologram.
Now we know how it works we can look at the uses of it. Well, it is used for data mining that is finding patterns in information. It is also used for petaflop computing that is trillion gilding operations per second. Therefore this is a very useful and effective way of storing data as well as exploring it.
