Abstract
Perpendicular recording media, where the CoCrPt-oxide recording layer is deposited on carbon based synthetic nucleation (SN) layers, have been proposed for recording applications and studied using first-order reversal curves for their magnetic interaction behavior. The magnetic properties of media with SN layer show better intergranular segregation whereas the media without SN layer shows otherwise. It is proposed that a dual SN layer structure, where an SN layer deposited above and below the high pressure sputtered Ru layer is suitable for achieving smaller grain size as well as better intergranular segregation.
