A tape data carrier for protecting articles and documents from counterfeiting and copying is formed by a polymer structure including at least one polymer layer of which at least one layer has at least one of through-perforations and pits. These through-perforations and pits are preferably between 0.001 .mu.m and 20 .mu.m in size and can be filled with different materials. The data carriers can carry concealed and visible macro-and micro- images created by heavy-ion bombardment of the polymer film, subsequent exposure of the bombarded film to ultraviolet radiation, and etching of the polymer film in a solvent. A device for manufacturing a data carrier of this type includes the following elements configured in series: a heavy ion source; a heavy ion beam-formation system; an ion guide; a three-dimensional amplitude modulation unit; and a target which is destined to become the data carrier. The three-dimensional amplitude modulation unit is designed to hold a matrix of wafers and is connected to a drive for rotating and translating the wafers. The drive is connected via a control unit to the three-dimensional amplitude modulation unit for positioning the target. |

DETAILED DESCRIPTION The given problem is solved by the fact that the information carrier is a film structure which comprises at least one layer of a polymer material having a relief surface formed by recesses and/or through-holes having the form of solids of revolution.
Recesses, through-holes and areas of a destructured polymer material have a diameter in the range of about 0.
001 .
mu.
m to 20 .
mu.
m on the surface of the polymer material and may have the same diameter and different depth.
At least a portion of recesses and through-holes may be filled with an anisotropic material, and/or a transparent, electrical conductive material, and/or a matter having magnetic properties, and/or a colouring matter, and/or hydrophobic or hydrophilic matter, and/ or luminescent matter, and/or a destructured material or the respective polymer layer.
The carrier layer system may comprise at least one layer of a magnetic material, and/or of a dichroic material, and/or hydrophilic or hydrophobic layer, and/or of a luminescent material, and/or a metal layer partially exceeding the layer of the polymer material and/or a thermoplastic material.
The film structure's layers may be made of polymer materials having different spectral characteristics and refraction coefficients.
The film structure may have on one of its sides a net of a polymer material or a metal having through-hole diameter equal or greater than 20 .
mu.
m.
Particularly, the net may be produced from the polyethyleneterephthalat.
The given problem is also solved by the fact that in the method for producing an information film carrier in which a step of forming marks on a polymer film having at least one layer is performed, in accordance with the invention the marks are formed by irradiating said polymer film with heavy ions to form a first concealed image, thereafter exposing said film to an ultraviolet radiation to form a second concealed image, and etching said film to create said marks in the form of recesses and holes.
The step of irradiating said polymer film may be performed with space-modulated heavy ions, for example, ions of carbon, chlorine, nitrogen, oxygen, and argon
