The relationship between crystallographic grain orientation and the three kinds of surface energy components; dispersion, polar, and hydrogen bonding components, in Co73Cr18Pt6Ta3 perpendicular magnetic recording media with an amorphous C or a Ti90Cr10 underlayer was discussed. Each surface energy component of the thin film was calculated from an extended Fowkes theory by measuring the contact angle of a test liquid on the thin film. The experimental results revealed that the polar component of surface energy of the Co73Cr18Pt6Ta3 magnetization film with the C underlayer affected greatly the Co [0 0 1] preferred orientation of the Co73Cr18Pt6Ta3 magnetization film, while the surface energy of the Co73Cr18Pt6Ta3 magnetic layer with the Ti90Cr10 underlayer had little influence on the distribution of it.
