CoCrPtO垂直介质的折射率大于6000 Oe，M/sub r/M/sub s/等于1.0，负成核场超过3000 Oe。的晶体学，磁性和记录性能进行了优化相对于Ru夹层和CoTaZr软底层的厚度。产生了具有小至7 nm的交换去耦磁性颗粒的介质，其具有能够支持高达720 kfci的线性密度的窄尺寸分布。在室温下，在50 kfci下测得的热衰减小于0.1%。
CoCrPtO perpendicular media with coercivities greater than 6000 Oe, M/sub r//M/sub s/ equal to 1.0, and negative nucleation fields exceeding 3000 Oe were produced. The crystallographic, magnetic, and recording properties were optimized with respect to Ru interlayer and CoTaZr soft-underlayer thicknesses. Media with exchange decoupled magnetic grains as small as 7 nm with a narrow size distribution capable of supporting a linear density up to 720 kfci were produced. Thermal decay measured at 50 kfci at ambient temperature was less than 0.1%.
