Device for writing and reading information from magnetic carrier that has flat magnetic carrier, writing block,-like writing head, one-slot reading heads, resonance amplifiers, phase detectors, threshold elements, elements NOT, elements AND, decoder and executive block, at that two additional one-slot reading heads are placed symmetrically with respect to axis of magnetic carrier as to two main heads, at that each of additional one-slot reading heads is connected to respective placed symmetrically reading head in series-reversed connection. Sixth and seventh one-slot reading heads are used. Those are placed in one plane symmetrically at both sides from axis of magnetic carrier at same distance with two main one-slot reading heads and displaced with respect to straight line along which three main one-slot reading heads are placed by distance that is equal to half of thickness of pole of writing head. Windings of one-slot reading heads symmetrical with respect to the straight line named are connected in series-reversed connection. |
