ABSTRACT A device for magnetic recording is provided with a layer of a magnetisable material provided on a support. This material has an easy axis of magnetisation which is perpendicular to the plane of the layer and the layer is suitable to support magnetic domains having a magnetisation direction which is opposite to the magnetisation direction of the remainder of the layer. The device contains a means for producing a magnetisation field having a field direction perpendicular to the plane of the layer, the layer being destined to cooperate with a recording medium which is relatively movable with respect to the layer, The device is characterized in that the layer of magnetic domain.
