Abstract: In the proposed method of manufacturing a magnetic recording medium, the first layer of the original material, is placed onto the substrate. A second layer of the second material is placed on the first layer. The thickness of the second layer is 3.8 nm or more. A lithographic mask with cavities according to the specified topology is placed on the second layer. The changes in the magnetic characteristics of the original material on the irradiated areas occur and provide for a plurality of magnetic elements. The magnetic characteristics of the original material in the areas protected by the lithographic mask are stored.

Abstract: An identification mark is disclosed comprising a substrate on which a plurality of code elements is arranged, each having a different coercive intensity in the external magnetic field of a given direction. Each code element comprises a low-coercivity layer, a nonmagnetic layer and at least a first group of discrete components arranged in a sequential order. Each discrete component is made single-domain from a magnetic material when magnetized in the easy direction, has the same size, shape anisotropy, coercive intensity, amount of magnetic material and arranged at the same distance to the neighboring discrete component from said first group of discrete components.

Abstract: An ion printer is proposed for simultaneous generation on the spatially fixed substrate of the whole image composed of micron and submicron size elements, containing a fixed substrate with layer of material capable of changing its properties under the ion influence; an ion source with a tool for beam forming, which ensures the divergence angle less than 20°, and with the first tool of acceleration of ions providing them the energy less than the one needed for variation of the properties of the material on the substrate surface. The said ion printer contains also a mask with parallel flat surfaces and with a ratio of its thickness to the distance from the mask to the substrate equals to 1:(0.6-3), correspondingly. The said mask has a plurality of apertures for passing the said accelerated ions, each of the apertures having the ratio of its depth to its cross-section size in the range from 9 to 50.

Abstract: A method of forming a three-dimensional structure consisting of plurality of areas with various physical properties includes deposition on a substrate of plurality of layers from a starting material capable of transforming its physical properties under irradiation by accelerated particles beam. In needed cases at least one layer of material is deposited, which is not capable of transforming its physical properties under the influence of specified accelerated particles beam.
