  • Magnetic recording device, especially for a hard disk and its manufacturing process
    Patent number: 8036070
    Abstract: A magnetic recording device comprising at least one unstructured recording support exhibiting at least one elementary magnetic layer, the recording support having a magnetization perpendicular to the plane of the support characterized in that it comprises magnetic elements having a magnetization perpendicular to the plane of the support and a greater inversion field than the inversion field of the recording support, and which are separated from the recording support by a decoupling layer made of a nonmagnetic material so that the magnetic elements produce a dipolar field in the recording support. The magnetic elements are spaced apart from one another by nonmagnetic regions, each magnetic element defining during a write operation a memory point in the recording support.
