Granular-type media with thin Ru intermediate layer were prepared on a highly oriented high-BsFeCo soft underlayer (SUL). A CoPt-TiO2recording layer on a Ru intermediate layer of only 2 nm had high-crystal orientation, high Hcof 6.5 kOe, and a high squareness ratio (SQ) of 0.99. The magnetic property of the SUL was also good. The recording performance was measured for the media with different Ru intermediate thicknesses by using a single-pole-type (SPT) head. The media had large reproduced output even for the Ru intermediate layer thickness of 2 nm. © 2008 Elsevier B.V. All rights reserved.
