FIELD: producing conducting layer of variable magnetization and coercive force along conductor or conductors by means of material spraying unit. ^ SUBSTANCE: proposed method for producing substrate to be used in code-dependent systems and locks incorporating provision for identifying not only shape but also magnetization distribution and coercive force of conductors includes formation of conducting layer on substrate by means of material spraying unit that has vacuum chamber, source of material to be sprayed, gas ion source at whose output ion arcs unequally bombard source of material to be sprayed so that stream of knocked-out atoms or ions of sprayed material on one end of source dominates over that of sprayed-material knocked-out atoms or ions on other end of source; conducting layer formed on sprayed substrate has varying magnetization and coercive force along direction of conductor or conductors. ^ EFFECT: enhanced reliability and protection of layers being identified against counterfeit. ^ 1 cl, 1 dwg |
