ROTATING WRITE MAGNETIC FIELD GENERATED BY CIRCULATING MAGNETIC DOMAIN WALL IN MAGNETIC RING, AND DC-DRIVEN HIGH-FREQUENCY OSCILLATOR

摘要

PROBLEM TO BE SOLVED: To provide a write process capable of switching a higher saturated holding force medium with a higher data rate.;SOLUTION: The apparatus includes a ring of magnetic material, a source for applying a setting magnetic field to the ring, and first and second electrodes for applying an electric current to the ring. A method of using the apparatus to write to a magnetic storage medium is also provided.;COPYRIGHT: (C)2007,JPO&INPIT
