Abstract :
Intermediate layers for perpendicular magnetic recording media have been studied for controlling storage layers with fine grains. The magnetic properties of the media was investigated for understanding the effect of the intermediate layer. H/sub c/spl perp// for the medium with the Pt/C intermediate layer showed a little bit large value compared with that with the Pt/Ti one. TEM images of the media were investigated. We show that platinum and carbon layers are suitable intermediate layers for a very fine Co-Cr-Pt-Nb storage layer in double layered perpendicular magnetic recording media.
