  • Data storage device with bit patterned media with staggered islands
    Publication number: 20070258161
    Abstract: A data recording device employs a bit patterned data recording medium that has an array of rows that are offset to one another. The rows are offset such that the bits are staggered in a direction that is normal to the direction in which the rows extend. The increased bit aspect ratio of the staggered bit pattern recording medium increases the linear recording density and enables a higher data recording rate.

  • Anti-ferromagnetically coupled soft underlayer
    Publication number: 20070065681
    Abstract: A magnetic recording medium having a first magnetic layer, a spacer layer, and a second magnetic layer, in this order, wherein the spacer layer includes a non-magnetic layer and a thickness of the spacer layer is selected to establish anti-ferromagnetic coupling between the first magnetic layer and the second magnetic layer, and a thickness of both the first and second magnetic layers are less than a critical thickness for formation of stripe domains in the magnetic layers is disclosed.

  • Granular perpendicular magnetic recording media with dual recording layer and method of fabricating same
    Publication number: 20060139799
    Abstract: A granular perpendicular magnetic recording medium comprises a non-magnetic substrate and a granular perpendicular magnetic recording layer overlying the substrate, comprising a first granular perpendicular magnetic layer proximal the substrate and having a first saturation magnetization (Ms)1, and a second granular perpendicular magnetic layer distal the substrate and having a second, different saturation magnetization (Ms)2. Also disclosed is a method of fabricating the granular perpendicular magnetic recording medium.
