Patent ID: 8169818

Claim:
A recording method for a magnetic memory device including (a) at least a recording layer that is (1) constituted of a ferromagnetic conductor, (2) capable of changing a magnetization direction, and (3) holds information as a magnetization direction of a magnetic body and (b) a magnetization reference layer whose magnetization direction is fixed and (a) that is provided with respect to the recording layer with an insulation layer interposed therebetween, (b) constituted of a ferromagnetic conductor, and (c) becomes a reference of the magnetization direction, the magnetic memory device being recorded with information by a current flowing between the recording layer and the magnetization reference layer via the insulation layer, the recording method comprising: 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, wherein, the one or more sub-pulses to be applied after the one or more main pulses is each a pulse (a) with a pulse width that is shorter than that of the one or more main pulses (b) with a pulse height that is smaller than that of the one or more main pulses, or (c) both.
