FIELD: equipment for magnetic and magnetooptical recording. SUBSTANCE: method involves doping substrate with ions of magnetic elements by means of ion-beam implantation. Power of ions of magnetic element is in range of 5-500 keV, in order to achieve 1020-1022 magnetic nuclei per cu.cm, density of ion beam is 6•1012-1•1014 ions per sq. cm, ions are implanted in polymer which at the moment of irradiation is in viscous relaxation phase with dynamic viscosity 101-103 Pa s. After implantation polymer is transferred to glass phase. EFFECT: increased magnetic characteristics, improved protection of near-surface layer of treated polymer.
