FIELD: information technology.
SUBSTANCE: invention relates to methods of recording information on a material object, intended for providing long-term storage on the surface of objects – from among objects (articles) obtained as a result of economic activities, as well as specially made for long-term storage of information, with the possibility of fast information acquisition during reading. For the first time, a method and a multi-beam system are proposed, which generates streams of parallel beams of low energy ions with their immediate delivery to the region of action for input of information organized bitwise in form of optimal size, number, direction of movement, average kinetic energy of clots (bunches) ions of contrast agent, implanted in near-surface layer of object, made in a single body (a multi-beam data insertion tool). In the case of a version for long-term archival storage of information, specially made plates which satisfy ×depending on the application. Two-way (through) reading from relatively large depth of recorded information requires transparency in ranges of electromagnetic spectrum used for reading, minimum number of chemical elements (isotopes) included in basic structure of base (substrate, information carrier), as well as minimum amount of impurities. Thus, recommendations for selecting a substrate in double-sided reading are transparency and purity (basic composition). Minimum thickness for information-significant layer of substrate substance is not less than 10 mcm at double-sided reading and not less than 30–50 mcm for layer providing stiffness and durability of carrier. In this case, the amount of information recorded on a quartz plate with dimensions of 10×10×0.01 cm3 (thickness of working layer of plate ~10 mcm, the remaining thickness for maintaining the plate stiffness during long-term storage), is about 1 petabit or about 10 terabit/cm2.
EFFECT: disclosed is a method for providing long-term storage of information on the surface of objects.
