FIELD: electronic engineering; magnetic data media. SUBSTANCE: method involves deposition of film varying its magnetic properties under effect of charged-particle flux onto substrate and formation of regular structure of single magnetic elements in this substrate by irradiating chosen areas. Novelty is that single magnetic element is formed with ratio of its larger size to each of two other ones being 3.5:1- 15:1 and thickness of deposited film equal to three sizes of element. Film may be made of material originally only slightly saturated or not saturated at all. EFFECT: enhanced density of data record items and storage reliability of medium. 2 cl, 3 dwg, 2 ex
