ABSTRACT:
A magnetic recording medium including a substrate having a surface, an orientation control layer disposed above the surface of the substrate, an underlayer disposed above the orientation control layer, and a recording layer having an hcp crystal structure and disposed on a surface of the underlayer. The recording layer is epitaxially grown on the surface of the underlayer to define a plurality of crystal grains, wherein the crystal grains have c-axes that are inclined in a plurality of random directions, but wherein each random direction defines an angle with respect to the surface of the substrate that is within a range that is greater than 0 degrees and less than or equal to 30 degrees. A magnetic storage apparatus including such a magnetic recording medium is also disclosed.
