Long-term storage of information: method and media.
Proposed a fundamentally new way of storing, recording, and reading information. Instead of the plastic CD-ROM drive uses a quartz disk. Information applied by laser on the surface and in the volume of the disc layers and also recorded the so-called nanorelay, so one point is recorded not one, but several (up to five) data bits. A fundamentally new method of recording information ensures the safety of millions and even billions of years.

Scientists proposed a fundamentally new way of storing, recording, and reading information. Instead of the plastic CD-ROM drive uses a quartz disk.
A fundamentally new method of recording information ensures the safety of millions and even billions of years.
A method of recording on the quartz differs from the recording on the CD-ROM because the information is applied by the laser is not on the surface and in the volume of the disc layers and also recorded the so-called nanorelay, so one point is recorded not one, but several (up to five) data bits.
This type of memory is called a multi-tiered voluminous memory. As a result, the volume of recorded data is obtained several times more. On such disk it is possible to store information of the order of terabytes of information (1 TB = 1024 GB). For example, on this disc you can burn about 500 movies or more than 200,000 archival documents. So, the archive of Gosfilmofond of Russia has 70 thousand titles of films, so they all fit on 140 CD-ROM instead of a huge archival storage with tape.
Besides quartz disk has a high degree of resistance to high pressures (up to 4,000 M) and temperatures (up to 900 0C) — can survive fire without loss of information. Not scary to him and also electromagnetic radiation.
Modern media live up to 10-20 years, after which the information should be written to another storage medium. Information with quartz disks do not need to rewrite.
Imported counterparts are limited in time (1000 years), cost, and resistant to fire and high pressures.
The principle of the recording method:
Under the action of femtosecond laser radiation in the oxide stacks of quartz glass are formed highly stable structures – nanolattice with the effect of birefringence of light. Each nanoresearch Pete is information – a point that receives data. Such terms modify the incident radiation of the reader in several dimensions, allowing you to encode several bits of data at one point (5D format).
– everlasting storage of information
– resistance to high temperatures,
– resistance to high pressure,
– the ability to store large amounts of information (terabytes of data),
– resistance to electromagnetic radiation.
Long-term archival data storage for:
– state archives,
– state library funds
– medical institutions
– organizations of the defense industry.
