FIELD: applied magneto-optics; read-out/record devices. SUBSTANCE: method is based upon relative movement of magnetic carrier and recorder, and on local effect of variable magnetic field onto magnetic carrier, which effect is formed by recorder. Local influence is made by at least with single pair of unlike pulses of magnetic field applied in perpendicular to plane of the carrier. Time interval between pulses of the pair is much more less then their duration. EFFECT: improved efficiency of operation. 8 cl, 3 dwg
