Abstract

A composite perpendicular medium with a (Co₇₂Cr₂₈)₇₈Pt₂₂ layer over a Cr-rich Co₇₂Cr₂₈ layer was fabricated to realize a high S/N in the high-recording density region by taking advantage of the strong particle interaction in the Co-rich CoCr layer. Characterization of the composite medium with a merged Mr head yielded an S/N of 24.0 dB at 200 kFCI and a D₅₀ of 205 kFCI, with a 50-nm magnetic spacing.
