Abstract
In a solid state magnetic memory device wherein the information storing region of a Bloch line memory device using Bloch lines generated in magnetic domain walls as information carriers is covered with a magnetic material film having stripe domains perpendicular to the magnetic domain walls, the information storing position is determined by the stripe domains and a memory density of more than several tens giga bits per cm.sup.2 can be realized.
