通过使用专为纵向记录设计的MR头来研究富Cr Co-Cr合金垂直介质中的介质噪声。 Cr 含量为 28 at.% 的介质表现出高晶体取向和低写退磁效应。该介质的信噪比（S/N）高于用于感应头的传统Co-Cr垂直介质。该介质的优点源于介质的大颗粒间垂直磁相互作用（/spl Delta/M/spl perp/），其随着Cr含量线性增加，在28 at.%时达到最大值。介质中的这种强烈相互作用导致使用单层垂直介质和 MR 磁头的记录系统具有高信噪比。
The medium noise in a Cr-rich Co-Cr alloy perpendicular medium was investigated by using an MR head designed for longitudinal recording. Medium with a Cr content of 28 at.% showed a high crystalline orientation and a low write-demagnetization effect. The signal-to-noise ratio (S/N) of the medium was higher than that of conventional Co-Cr perpendicular media for inductive heads. The advantages of the medium derive from the large inter-particle perpendicular magnetic interaction (/spl Delta/M/spl perp/) of media, which increased linearly with the Cr content, reaching a maximum value at 28 at.%. This strong interaction in the medium results in a high S/N for a recording system using a single-layer perpendicular medium and an MR head.
