A new granular-type perpendicular magnetic recording media was designed to reduce the intermediate layer thickness. A medium with Ru intermediate layer of only 2 nm was prepared successfully on a highly oriented high-B_s FeCo soft underlayer (SUL). The CoPt-TiO_2 recording layer had a high crystal orientation, a high H_c of 6.5 kOe, and a high squareness ratio of 0.99. The magnetic property of the SUL was also good. The granular structure of the CoPt-TiO_2 recording layer in the new-designed medium is similar to that in the old-designed one.
