Holographic data storage devices Computer science essay
Holographic data storage system HDSS has been a good candidate for a volumetric recording technology, due to their large storage capacities and high transfer rates, and has been explored for decades after the principle of holography was first proposed. However, these systems, called -axis holography, still have the potential to be studied in computer science because of the endless possibilities it offers, the intellectual challenge it provides and the collaborative nature of the field. I am excited to embark on this journey of exploration and discovery, knowing that through my work in technology I will be able to make a positive impact in the world. Holographic data storage is a promising technology that offers very large data storage capacity, and the multiplexing method plays an important role in increasing this capacity. Various multiplexing methods have been previously investigated. In the current study, we propose a shift-peristrophic multiplexing technique using 2. Floppy Disks. Also known as a floppy disk, floppy or FD, the floppy disk is another type of storage medium that uses magnetic storage technology to store information. Floppy disks were once a common storage device for computers and were very common from the mid-1970s to the turn of the century. Volume holographic storage technology has the advantages of high storage density, huge data capacity, parallel reading and writing, fast transmission speed and so on. In the Big Data era, this method has great potential to meet the needs of low cost and low storage density. Holographic storage devices made of photopolymer materials, on the other hand, allow conventional storage devices to record or retrieve the data one bit at a time. Therefore, holographic storage devices greatly improve data transfer speeds. The combined benefits of high data transfer speeds with durable and reliable storage media will certainly make this technology an attractive choice. Previous studies have shown that orthogonal phase encoding multiplexing performs well with low crosstalk in conventional off-axis systems. However, noticeable crosstalk occurs when applying orthogonal phase encoding multiplexing to collinear holographic data storage systems. This paper demonstrates crosstalk generation. Holographic optical storage is a strong candidate for the next generation of massive data storage, due to its high data transfer rate, high storage capacity and long storage duration. 1, 2, 3.
