简化的Neel-Arkenius分析用于确定纵向和保持垂直介质的极限密度与SNR。主要的过渡噪声被假定和晶粒尺寸分布和存储在室温以上的影响。周向记录可能比纵向记录具有更高的密度;例如，在SNR=20 dB时，极限密度分别约为500和100 Gbit/in/sup 2/。
Simplified Neel-Arrhenius analysis is utilized to determine limiting densities versus SNR for longitudinal and keepered-perpendicular media. Dominant transition noise is assumed and the effects of grain size distribution and storage above room temperature are included. Perpendicular recording potentially exhibits a higher density than longitudinal; for example, at SNR=20 dB, the limiting densities are approximately 500 and 100 Gbit/in/sup 2/, respectively.
