我们提出了动态写入/读取特性的氧化铝纳米孔图案化介质具有软磁衬层（SUL），它提供了良好的飞行能力的垂直磁头飞行高度为10 nm。通过测量信噪比和孤立磁过渡宽度，证实了由于SUL在记录层中的头场梯度的增加。磁性纳米柱的可写性通过用磁力显微镜观察记录的图案而清楚地证明
We present dynamic write/read characteristics of alumina nanohole patterned media having a soft magnetic underlayer (SUL), which offer good flyability of a perpendicular magnetic head with a flight height of 10 nm. Increase in the head-field gradient in the recording layer owing to the SUL was confirmed by measurements of signal-to-noise ratio and isolated magnetic transition width. The writability of the magnetic nanopillars was clearly demonstrated by visualization of the recorded patterns with a magnetic force microscope
