Definitions

• the utility model belongs to information technology and can be used in data storage systems.
• the proposed medium relates to reusable and rewritable media.
• optical media in particular, compact discs
• information is recorded on a photosensitive layer deposited on a substrate with tracking tracks.
• Service information is also recorded in the tracking track (about the type of medium, manufacturer, as well as synchronization marks).
• optical media with one-time recording such as CD-R, DVD-R, BD-R
• CD-R, DVD-R, BD-R are created, into which recording is carried out by creating micro-holes (pits), or media with reusable recording (type CD -RW, DVD-RW, BD-RE), in which recording is carried out due to the reverse phase transition between the amorphous and polycrystalline phases in semiconductor materials.
• CD optical media
• Such media are widely used to record information in digital form, however, they do not provide long-term data storage. This is primarily due to the physicochemical characteristics of the linings made of polycarbonate. In the process of long-term preservation, an uncontrolled change in the size and shape of the formed microrelief structures (tracks, pits, prints) occurs. Repeated reproductions of recorded information due to local temperature increase also lead to deformations of microrelief structures created on the surface of the carrier, using which the information presented on the carriers is encoded.
• DNA molecule stores information in the quadruple number system, according to the number of nucleotides (0 - A, 1 - T, 2 - C, 3 - G). This is a very compact container with a recording density a thousand times greater than that of today's known carriers.
• DNA as a storage medium is based on coding technology that allows you to convert kilobytes of information into a genetic code and vice versa. If information is stored on a digital medium in the form of a sequence of zeros and ones, then DNA is recorded using a sequence of nucleotides.
• Tight packaging (1 g of DNA is equivalent to approximately 1 million CDs);
• the purpose of the claimed utility model is to develop a storage medium that can accommodate a large amount of data, save this data for an almost unlimited period, with the ability to replenish information, quickly search and read information.
• Such a carrier are plant polypeptides. It was found that polypeptides of small sizes, the molecular mass of which is in the range from 1 to 150 kDa, and the primary structure contains from 1 to 10 amino acids, when certain conditions and organizations are created, can create a data bank in which you can write and save very large volumes of information. These volumes of data can be compared with the volumes of data contained in tens of billions of media (CD-R, DVD-R, BD-R).
• the inventors found that if the polypeptides of plant origin are given the form of a liquid crystal in an aqueous buffer solution, then this form allows: firstly, to maintain a stable structure, external size, secondly, to preserve the natural activity of the polypeptides, thirdly, it does not limit the ability to exchange information with such a medium, i.e., the ability to write and read information, fourthly, to save the above capabilities for an almost unlimited time.
• a liquid crystal is used from plant polypeptides of small sizes, the molecular weight of which is in the range from 1 to 150 kDa, and the primary structure contains from 1 to 10 amino acids.
• the procedure for creating liquid crystals from various substances is known to those of ordinary skill in the art.
• the procedure for giving the polypeptides a mesomorphic form, i.e. type of liquid crystal includes a sequence of technological operations for which, in addition to direct operations, additional indicators are also important: temperature conditions, the duration of each of the individual operations, sterility, etc.
• the procedure for creating a liquid crystal from plant polypeptides includes the following operations:
• the extracting solution contains, for example, 0.9% NaCl in 0.004 M potassium phosphate buffer
• composition was determined using high performance liquid chromatography (HPLC) followed by tandem mass mass spectrometry using an LTQ FT ICR mass spectrometer (Hybrid-2D-Linear Quadrupole Ion Trap, Fourier Transform Ion Cyclotron Resonance Mass Spectrometer), which allowed the identification of peptides that did not assigned to known polypeptides and proteins.
• the molecular weight of such peptides is generally in the range of 1 to 15 kDa. The inventors admit that it is this part of the peptides that can accommodate huge amounts of information, since they are the most “clean” or “empty”, i.e. most suitable for recording information.
• liquid crystal from polypeptides can be attributed to the group of smectic liquid crystals, which are the most crystalline among other liquid crystals.
• Somatic crystals are characterized by two-dimensional ordering. Molecules are placed so that their axes are parallel. Moreover, they “understand” the “equal” command and are placed in slender rows packed on smectic planes, and ranks on nematic planes. The presence of long-term memory is characteristic of smectic liquid crystals.
• polypeptides consist of a sequence of amino acids that can be used as “empty” cells for recording, storing and reading information. Since twenty amino acids are currently known, this makes it possible to use a twenty base number system. Such a number of discharges makes it possible not only to record information converted from a binary (digital) system into an amino acid sequence, but also to use some amino acids as auxiliary ones, which, in turn, saves space when recording repetitions of amino acid sequences.
• the inventors have proposed the use of a hexadecimal number system for recording information. It is clear that, in general, the base of the number system may to be different, but in this particular case (variant) of use, the inventors proceeded from the fact that the first (or any) sixteen amino acids can be used as informational, and the last (or any) four amino acids (T, V, W, Y) can be used as official . This number system is also used by inventors to write and read large amounts of information. The proposed number system does not limit the ability of inventors to use number systems for other reasons.
• the ASCII coding system is selected, however, in general, another system can be selected, for example, HTML code, etc.
• a new code is used, the essence of which is to split into a large number of overlapping small fragments and their indexing (addressing), indicating the reading sequence.
• This code is designed to prevent the repetition of characters.
• the developed code is one of the possible encoding options, is given only to demonstrate the benefits of coding using an amino acid sequence, and does not limit the rights of inventors to use other coding approaches.
• Mukaltin (100% consists of components of plant origin)
• Acyclovir has a purely chemical origin
• Glucofage contains components of both natural and artificial origin
• the sizes of the obtained sequences were approximately 700 MB for Mukaltin and Glucofage, respectively, and about 4 TB for Acyclovir.
• the obtained information was used as experimental to verify the recording on the claimed medium and the correct reading of information from it.
• Modern technologies increasingly include devices and tools using laser and fiber optic technologies.
• the combination of these technologies and other well-known technologies for recording / reading information in the near future will lead to the emergence of new devices with qualitatively new super-powerful characteristics: write and read speed, recording density of information, the duration of information storage, etc.
• the fiber optic system includes collecting and scattering lenses, a red laser and optics for writing / reading. At the same time, a collecting lens is used to record data, and a diffusing lens is used to read data.
• the technology of recording / reading is based on the use of "biological waves", which allows the use of ultrahigh speeds, both for recording and for reading information. It is possible to use both individual heads for recording and reading information, or a unique head with integrated optics combining the functions of writing and reading, which accurately directs the laser beam to the desired section of the information carrier.
• the storage medium according to the claimed utility model can be used in data storage and processing systems, and also, subject to the development of specialized equipment, become the basis for new generation high-speed computing systems and find its place in new information technologies.
