FIELD: electrical engineering; producing magnetic media for high-density data recording. SUBSTANCE: proposed method is characterized in that in the course of production of magnetic matrix which is, essentially, magnetic film, areas with magnetic state other than that of matrix are entered therein, their dimensions ranging between a few 10-10m and 50 nanometers; they are produced as result of introduction of dopes or crystalline structure defects in magnetic matrix. EFFECT: facilitated production of magnetic material for high-density data recording. 7 cl
