Abstract
Co-Ni-Re-Mn-P and Co-Ni-Re-P alloy films for perpendicular magnetic recording media were prepared by an electroless plating method, and the effect of film thickness on magnetic properties and recording characteristics was investigated. This effect was found to differ greatly for the two alloy systems. In the case of Co-Ni-Re-Mn-P alloy films, the perpendicular anisotropy magnetic field (H//k) and the perpendicular coercivity H//c( PERPEND ) decreased with decreasing film thickness, and suitable magnetic properties could not be maintained for films thinner than 0. 2 mu m. However, in the case of Co-Ni-Re-P alloy films, the values of H//k, H//c( PERPEND ), and perpendicular anisotropy energy (K//u) increased with decreasing film thickness, and magentic properties suitable for perpendicular recording were obtained in the thinner films.
