Abstract

The realization of perpendicular magnetic recording critically depends on the reduction of medium noise. The CGC media structure with a continuous layer and a granular layer is a candidate for attaining high SNR. The noise characterization of the CGC double-layered media is described by focusing on the transition jitter and magnetization transition analysis using an MFM. CGC media with three different thickness (1.2, 3.6, 6 nm) of the Co/Pt continuous layer were used in this study. All of them had the same 15 nm granular layer. The plain granular medium was chosen as a reference. A single-pole head was used for writing.
