This is the authors' abstract. We don't add key points for this paper.
High S/N media, composed of Co-Cr-Pt/Co-Cr-Pt-Si dual-layered films with isolated grains, are developed for ultra-high density longitudinal recording. C/Co-Cr-Pt-Si/Cr media have a low-noise characteristics. By changing the upper Co-Cr-Pt-Si layer to a Co-Cr-Pt layer, low-frequency output is increased by 30%. The isolated grains are produced by high Ar pressure (28 mTorr) in the Cr-underlayer deposition. When these media are combined with a narrow-track dual-element head, a high areal density of 2 Gb/in2 is realized in combination with modified signal processing and optical head-positioning.
