Abstract

Benchs for research of the parameters defining stability of magnetic properties of thin-film materials of the modern hard magnetic disks in case of impact on them of a constant magnetic field are developed and created. Techniques of determination of the magnetic fields providing guaranteed erasing of information from carriers on rigid magnetic carriers (NGMD) are developed, a technique of monitoring of a completeness of erasing of information on the basis of atomic force microscopy (ASM), value of an outside influencing constant magnetic field exceeding value of coercive force of a thin-film magnetic material effectively and safely erasing information from magnetic carriers is defined.

Keywords:

thin-film material, magnetic disk, coercive force, atomic force microscope, information erasing, magnetic relief, magnetization method, microprobe, kantilever, nanostructure, record fragment.
