    The invention relates to the field of information storage, namely to the working layers of video clips. A working layer of a video plate, which is filled with a spiral information groove, is known, which makes it possible to ensure a relatively high accuracy corresponding to the relief of the spiral information field of the recorded information f 1. The disadvantage of this working layer is the considerable complexity of the process of recording information on the Internet. Also known is a working layer of a video plate, made with a spiral information groove, imegatsii specific volume resistance of less than 500 ohms / cm at a frequency of 900 MHz and consisting of particles of gas soot distributed in the bond material. This working layer makes it possible to ensure the relative simplicity of the process of recording information on it 2. A disadvantage of the known working layer is a considerable increase in the deformation upon heating. This is due to the properties of the bonded material in which part of the gas soot is distributed. invention - reducing deformation when heated. The goal is achieved by the fact that in the working layer of a video plate, made with a spiral information groove, having a specific volume resistance of less than 500 Ohms / s at a frequency of 900 MHz and consisting of carbon black particles distributed in the bonding material, the bonding material contains methyl methacrylate copolymer with styrene, chlorinated paraffin j dibutyl-tin-mercaptoproshgonate, dibutyl tin maleate, barium and lead stearate, glyceryl tribenzoate, epoxidized soybean oil, phthalase layer, mixture of fatty acids and complex of monohydric acid ester from alcohols of various molecular weights, a mixture of phthalic acid esters, calcium stearate, esterified mountain wax and polyvinyl chloride polymer at the following ratio of components, wt.%: Gas particles 12.0-20.0 carbon black Methyl methyl methacrylate copolymer 1.0-7.0 with styrene Chlorinated paraffin1.0-2.0 Dibutyltin-f -mercaptopropionate1, 0-3.0 Dibutyltin maleate1, 0-2.0 Barium and lead stearate 0.5-2, 0 Glyceryl tribenzoate 0,25-1,50 Epoxidized soybean oil 1,0-2,0 Phthalate plasticizer1, 0-5,0 Mix of fatty acids and layer mono-fatty acid ester from alcohols of various molecular weights 0.25-0.75 Phthalic acid ester mixture 0.25-0.75 Calcium stearate 0.3-1.0 Esterified hot wax 0.2-0.5 Polyvinyl chloride polymer The rest of the proposed working layer may contain, wt.%; carbon black particles (2.0, methyl methacrylate copolymer with styrene 1.0, chlorinated paraffin 1.0, dibutyltin / mercaptopropionate 1.0, dibutyltin maleate 1.0, barium and lead stearate 0.5, glyceryltribenzoate 0.25, oxidized soybean oil 1.0, phthalate Hbttt. plasticizer 1.0, a mixture of fatty acids and mono-fatty acid ester from alcohols of different molecular weights 0.25, a mixture of phthalic esters 0.25, calcium stearate 0.3, esterified mountain wax 0 , 2, polyvinyl chloride polymer 80.25, The proposed working layer may also contain, wt%: carbon black particles 20.0, methyl methacrylate copolymer with styrene 7.0, chlorinated paraffin 2.0, dibutyltin-β-mercaptopropionate 3.0, dibutyltin maleate 2.0, barium stearate 2.0, glyceryltribenzoate 1.5 , epoxidized soybean oil 2.0, phthalate plasticizer 5.0, a mixture of fatty acids and mono-fatty acid ester from alcohols of various molecular weights 0.75, a mixture of phthalic acid esters 0.75, calcium stearate 1.0, esterified mountain wax 0.5, polyvinyl chloride polymer 52.50. The proposed working layer may, in addition, contain, wt%: carbon black particles 15.0, methylene methacrylate copolymer with styrene 3.0, chlorinated paraffin 1.5, dibutyltin-: -mercaptopropionate 2.0, dibutyltin maleate 1.5, barium stearate and -lead 1.0, glyceryl tribenzoate 1.0, epoxidized soybean oil 1.5, phthalate plasticizer 3.0, a mixture of fatty acids and mono-fatty acid ester from alcohols of various molecular weights 0.5 , mixture of phthalic acid esters 0.5, calcium stearate 0.75, esterified hearth wax 0.3, polyvinyl chloride polymer 68.45. When the content of carbon black particles, a copolymer of methyl methacrylate with styrene, chlorinated paraffin, dibutilolovo- -merkaptopropionata, dibutilolovomaleata, barium stearate and lead glitseriltribenzoata, epoxidized soybean oil, phthalate plasticizer, fatty mixture ki lot and complex monofatty acid ester of alcohols of varying molecular p1 3 mass, mixtures of phtanoy lovic acid esters, calcium stearate, esterified mountain wax and polyvinyl chloride polymer are less respectively 12,, 0; 1.0; , 1.0; t, 0; 1.0; 0.5; 0.25; 1.0; 1.0; 0.25; 0.25; 0.3; 0.2 and 52.50 wt.% Or more, respectively, 20.0; 7.0, 2.0; 3.0; 2.0; 2, 5; 2.0; 5.0; 0.75; 0.75; 1.0; 0.5 and 80.15 wt.% To a large extent either we use the electrical properties of the working layer of the video plate, or the deformation increases when heated, or its other properties deteriorate. The pre-working layer allows to ensure high accuracy of matching the relief of the spiral information groove of the recorded information. This, in turn, makes it possible to ensure high accuracy of the recorded information with the reproduction result obtained due to the effect of the relief of the spiral information groove and the needle of the reproducing element. The use of the invention allows to significantly reduce the deformation of the working layer of the video plate when heated.
