摘要：

We have fabricated Co/Pd, CoCr/Pd, and CoCrTa/Pd multilayer media. Good recording performance was achieved using a magnetoresistive (MR) head for readback. Co/Pd medium has perpendicular coercivity of 5 kOe and perpendicular squareness ratio of 0.83. The recording performance of a Co/Pd multilayer media was compared to conventional longitudinal media Co86Cr10Ta4 media and perpendicular Co78Cr17Ta5 media. The effects of Cr doping of Co, postdeposition annealing of Co/Pd, annealing the plated NiFe keeper layer, the number of layers in the multilayer, and the oxygen concentration of sputtering gas on the noise spectra of media were studied.
