A recording medium according to the invention has a magnetic recording layer with an L10 magnetic material deposited with a (111) preferred orientation and soft underlayer (SUL). One set of embodiments includes an intermediate layer (seed layer or underlayer) between the L10 media and SUL. The intermediate layer can be a close-packed surface structure (triangular lattice) to promote (111) orientation of the L10 media. For example, the intermediate layer can be a (111) oriented, face-centered-cubic (fcc) material such as platinum, palladium, iridium, rhodium, FePt, FePd, or FePdPt alloys; or the intermediate layer can be a (100) oriented hexagonal-close-packed (hcp) material such as ruthenium, rhenium, or osmium. Alternatively, the intermediate layer can be an amorphous material. The L10 recording layer of the invention can be deposited with a matrix material to form grain boundaries and provide magnetic isolation of the grains of L10 material.
