The binary information readout device comprises a recoder element arranged as a record head connected with a code shaping unit output, two reading elements made as reading heads, the outputs being connected to corresponding recording unit inputs where the first reading head is made as two-slotted, the second reading head is arranged as single-slotted and biased with regard to the first reading head along the information carrier axis for a value equal to a half of record head pole thickness. The device is provided with the additional third reading head arranged as single slotted and located on one axis with the first reading head across the information carrier as well as biased with regard to it for a value equal to a half of record head pole width. Winding of the second and third reading head are in series connected among them. |
