Abstract

A recording method for a magnetic memory device that includes applying, when recording one piece of information, one or more main pulses and one or more sub-pulses in the same direction and applying the one or more sub-pulses after the one or more main pulses, the one or more main pulses each being a pulse that has a sufficient pulse height and pulse width to record information, the one or more sub-pulses each being a pulse that satisfies at least one of conditions that a pulse width is shorter than that of the one or more main pulses and that a pulse height is smaller than that of the one or more main pulses.
