A process of fabricating a perpendicular magnetic recording medium. In one embodiment, the process may comprise forming a metallic buffer layer with a (002) texture on an underlayer using a deposition process performed at a temperature below 30&#xb0; C. The underlayer may have a crystalline (001) texture. The process may further comprise forming a perpendicular magnetic recording layer on top of the metallic buffer layer using a deposition process performed at a temperature above 350&#xb0; C. The magnetic recording layer may comprise a magnetic material with a L1crystalline structure and with a c-axis perpendicular to a plane of the perpendicular magnetic recording layer. The process may further comprise removing metal of the metallic buffer layer from a top surface of the perpendicular magnetic recording layer that moved to the top surface of the perpendicular magnetic recording layer during the forming of the perpendicular magnetic recording layer.
