  • Patent number: 9431046
    Abstract: A perpendicular magnetic recording (PMR) disk has a patterned template layer for the growth of the magnetic grains and the nonmagnetic material surrounding the grains. The template layer is a substantially planar platinum (Pt) or palladium (Pd) layer that is patterned to have Pt or Pd regions arranged in a hexagonal-close-packed (hcp) pattern with the Pt or Pd regions surrounded by Pt-oxide or Pd-oxide regions. The two separate regions of the template layer have different surface chemistries and energies, which provide a “chemical contrast” to impinging atoms during deposition of the metallic magnetic material and nonmagnetic (typically oxide) material, effectively guiding the deposition. The metallic magnetic material is preferentially deposited on the pristine, epitaxial Pt or Pd regions to form the magnetic grains, while the oxide migrates to the oxidized Pt or Pd regions due to the matching of lower surface energy.

    Abstract: The present disclosure relates to a method for fabricating an ion-implanted bit-patterned medium. The method includes providing a medium, the medium having a magnetic layer and a substrate and the magnetic layer includes migrating components. The method further includes forming a patterned mask layer on the surface of the magnetic layer and then ion-implanting the medium through the patterned mask layer, wherein the exposed portions of the magnetic layer comprise trench regions, the covered portions of the magnetic layer comprise island regions, and the transition areas between the trench regions and the island regions comprise boundary regions, wherein the island regions have more favorable magnetic properties than the trench regions. The method also includes annealing the medium, wherein the migrating components diffuse from inside the island regions towards the trench regions.

  • Patent number: 9224412
    Abstract: A continuous-media perpendicular magnetic recording disk has a granular recording layer (RL) with controlled grain pitch distribution and controlled long range ordering of the grains. The disk includes a substrate with a template layer for the RL that comprises a blend of at least two different sized nanoparticles. The nanoparticles have a nanoparticle core with attached polymer ligands. The nanoparticle cores protrude above the surface of the template layer to provide a nonplanar surface topology. The blend of two sizes of nanoparticles causes the RL to have low grain pitch distribution and a disruption of long range ordering so that there are no large magnetic rafts.
