我们提出了一个比特模式媒体记录的面密度势的综合分析。记录性能受写入误差的影响，而不是传统的信噪比考虑。写入误差是由各个点的磁性和位置的统计波动引起的。利用磁头、软磁衬层和复合型存储介质的组合获得最高的面密度。分析了高达5 TB/英寸(2)的面密度情景。
We present a comprehensive analysis of the areal density potential of a bit-patterned media recording. The recording performance is dominated by written-in errors rather than traditional signal-to-noise considerations. Written-in errors are caused by statistical fluctuations of the magnetic properties and the locations of the individual dots. The highest areal densities are obtained with a combination of a pole head, a soft magnetic underlayer, and a storage medium of the composite type. Areal density scenarios of up to 5 Tb/in(2) are analyzed.
