Patent ID: 6986954

Claim:
A magnetic recording medium comprising: a substrate; a seed layer of titanium formed over the substrate, the seed layer of titanium including hexagonal close pack (HCP) crystallites in a (0001) orientation; a seed layer of platinum formed over the layer of titanium, the seed layer of platinum including face centered cubic (FCC) crystallites in a (111) orientation; and a multi-layered magnetic stack formed over the layer of platinum, wherein the multi-layered magnetic stack includes a plurality of layers each having a thickness of less than or equal to approximately 3 nanometers, and wherein the multi-layered magnetic stack comprises pairs of alternating layers including face centered cubic (FCC) crystallites in a (111) orientation, wherein each of the pairs defines a period of the multi-layered magnetic stack, and wherein the medium exhibits a coercivity greater than or equal to approximately 3948 Oersteds and a hysteresis curve having a nucleation field greater then 80 percent of its coercivity.
