In this study, the effects of CoCrPtTa and CoCrPtB magnetic intermediate layers (IL) on the magnetic properties and read/write performance of CoCrPt/soft magnetic layer perpendicular recording media were investigated. Even though the perpendicular coercivity of the media with these IL was reduced by 500 Oe, these media still showed low exchange slope of 1.6 and large negative nucleation field of about -1000 Oe. Additionally, the reduced grain size of the media with these IL was observed by TEM. From the read/write test, these media with IL showed improved performance of 3〜5 dB higher SNR and OW compared to the media without IL. These enhancements could be attributed to the reduction of grain size of the magnetic layer and weakening of intergranular interaction between grains by insertion of the IL.
