Rosetta Disk

Rosetta Disk have a new high density analog storage device as an alternative to the quick obsolescence and fast material decay rate of typical digital storage systems. This technology, developed by Los Alamos Laboratories and Norsam Technologies, can be thought of as a kind of next generation microfiche. However, as an analog storage system, it is far superior. A 2.8 inch diameter nickel disk can be etched at densities of 200,000 page images per disk, and the result is immune to water damage, able to withstand high temperatures, and unaffected by electromagnetic radiation. This makes it an ideal backup for a long-term text image archive. Also, since the encoding is a physical image (no 1's or 0's), there is no platform or format dependency, guaranteeing readability despite changes in digital operating systems, applications, and compression algorithms.

Data Now can be saved on a Drop of DNA of your body

In the new study, researchers from Columbia University and the New York Genome Center ( NYGC ) demonstrated that the algorithm for streaming video on the smartphone can be almost fully unlock the potential of DNA storage and compression of additional information in the four nucleotide bases.   The idea and the general considerations of the recording, storage and retrieval of information in DNA molecules belong to Michael Neumann - Soviet scientist and physicist. In 1964, the magazine "Radio" published an article, which describes the technology of the process and data storage device - Neumann oligonucleotides (MNeimON).  In 2012, geneticists at Harvard University was able to encode a draft of a book of 53,400 words, 11 images and one program. They found that in each cubic millimeter of DNA can be stored 5.5 petabytes of data. A year later, the researchers of the European Bioinformatics Institute managed to save, and then completely remove and play about 0.6 megabytes o...
