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 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. It comprises third reading head made as single-gap one and placed on the same axis with first reading head across data carrier and displaced relative to it by value equal to half-thick of writing head pole. Windings of first and third reading heads are connected among themselves in series. Additional fourth reading head is used, this is made as single-gap one and placed at the same plane with first and third reading heads, which is perpendicular to magnetic carrier axis. Windings of first, third and fourth reading heads are connected in series among themselves. |
