Abstract

This work presents the research results of information erasing from modern multidisc HDDs by pulse magnetic fields. The quality of information erasing was assessed by methods of atomic force microscopy. The island character of information erasing is explained by shielding of magnetic impulse by metal elements of HDD design. Amplitude and time characteristics of magnetic pulses needed for reliable information erasing from modern multidisc HDDs are defined.
