Abstract
There is provided a magnetic storage disc comprising a heat-assisted magnetic recording structure comprising an adjoining ferromagnetic sputtered layer and antiferromagnetic sputtered layer magnetically coupled to each other by a magnetic exchange interaction giving rise to exchange bias, wherein the anisotropy axis of the antiferromagnetic sputtered layer is configured to be perpendicular to at least one seed layer disposed between the antiferromagnetic sputtered layer and a supporting substrate. A magnetically soft layer is disposed between the antiferromagnetic sputtered layer and the at least one seed layer. A method of forming a magnetic recording disc is also provided.
