The recording and magnetic carrier-information readout device comprises a record block connected with a record head, three single-slotted read heads, two of them are symmetrized with regard to a magnetic carrier axis equal to a half of a gap width of the record head and a half of a gap width of its pole and another record head located on the magnetic carrier axis, - along the magnetic carrier axis equal to a half of width of the record head pole, the single-slotted read heads are in series connected by resonance amplifiers, phase detectors and threshold elements, the outputs through NOT and AND gates being in series connected to a decoder and an executive unit, where the symmetrized single-slotted read heads windings are anti-parallel series connected. The device are provided with an additional fifth an sixth read heads symmetrically with regard to a major single-slotted read head located on the magnetic carrier axis in the distance equal to a half to working gap width of the record head and a half of its pole width. These read head windings are anti-parallel series connected. |
