Abstract
A magnetic storage medium includes first and second magnetic layers provided on a support substrate such that the first and second magnetic layers have respective first and second magnetizations in an anti-parallel relationship in a state no substantial writing magnetic field is applied. The first and second magnetizations are changed to a parallel relationship when a writing magnetic field is applied to the magnetic storage medium, and the first and second magnetizations are changed to the anti-parallel relationship as a result of a magnetic reversal caused in the second magnetic layer with diminishing of the writing magnetic field. The reversal is caused as a result of the action of a reversing magnetic field that dominates before the writing magnetic field is diminished and becomes zero.
