FIELD: physics, computer technology.
SUBSTANCE: invention concerns information recording and reading. Microasperities are made on object surface at given pitch and depth around labels to ensure non-glare reflection of sounding irradiation. Sounding irradiation is projected to coded structure. Image of 3D labels in the form of surface indents is read. Label surface parameter deviation from determined microasperity 4 parameters of surface 1 around labels is defined during reading.
EFFECT: enhanced interference resistance of coded information recording and reading.
