MAGNETIC STORAGE DEVICE, PARTICULARLY FOR A HARD DRIVE, AND METHOD FOR MAKING SAME

摘要

The invention relates to a magnetic storage device that includes at least one non-structured storage medium having at least one elementary magnetic layer, said storage medium having a magnetisation perpendicular to the plane of the medium, characterised in that it comprises magnetic elements (46) having a magnetisation perpendicular to the plane of the medium and a reverse field higher than the reverse field of the storage medium, and separated from the storage medium by a decoupling layer (47) made of a non-magnetic material so that the magnetic elements (46) generate a dipolar field in the storage medium, the magnetic elements (46) being separated from each other by non-magnetic regions (41), wherein each magnetic element (46) defines a memory point in the storage medium (43) during a writing operation.
