A device for reading out binary information comprises a recording element arranged as writing head connected to output of code former, two reading elements arranged as reading heads which outputs are connected to corresponding inputs of the recording unit. First reading head is made as double-gap one, second reading head are single-gap one and displaced by axis relative to the first head along the magnetic carrier by value equal to half-thick of writing head pole, third reading head is made as single-gap one and placed on the same axis with first reading head. Amplitude detectors, adder and additional fourth and fifth double-gap reading heads are used. Fourth and fith heads are displaced relative to the first double-gap reading head by value equal to the half-width of bit interval, outputs of those ones are connected through the amplitude detectors to the adder connected to additional threshold element. Outputs of the executive unit are connected to the additional threshold element and to outputs of additional AND gates which one input is connected to the additional threshold element , and second input is connected to the output of the main AND gate. |
