A device for reading information from magnetic carrier includes two reading elements placed in normal to each other planes, binary code former connected to reading elements, threshold element, element AND, and executive block, amplitude detectors, adder and additional reading elements placed in the carrier plane, in parallel and symmetrically with respect to one of the main reading elements at distance equal to width of order interval, the outputs of those through amplitude detectors are connected to the adder connected to the threshold element, the inputs of the executive block are connected to the threshold element and to the element AND, one of the inputs of this one is connected to the threshold element, the second one – to the binary code former, additional reading element placed in the plane of the opposite side facet of the carrier at one straight line with the main reading element, and the windings of those are in series opposite connection, counter of information pulses counter input of which is connected to the binary code former, control input – to the threshold element, and the outputs – to executive block. Additional reading elements are used, those are placed at the opposite side of the magnetic carrier at same axes with the main reading elements, at that the windings of the additional reading elements are connected in pairs in series opposite connection. |
