AbstractEffects of plating conditions on Co ferrite-plated films for perpendicular magnetic recording media were investigated to increase coercivity H c⊥ and remanence ratio (M r/M s) ⊥ in the plane perpendicular to the film. By optimizing a concentration of NaNO 2 in an oxidizing solution and the deposition rate, Co-Ni ferrite films with H c⊥ of 3200 Oe and (M r/M s) ⊥ of 0.6 were obtained without any heat-treatment. Disk media with higher H c⊥ and (M r/M s) ⊥ exhibited reproduced waveforms of di-pluses shape and better frequency responses than that with lower H c⊥ and (M r/M s) ⊥. Media noise did not increase with increasing frequency, suggesting that the transition noise was low. © 1999 IEEE.
