在垂直磁记录中，介质噪声是限制可达到的密度的关键问题之一。本文的目的是为降低介质噪声找到一个指导原则。虽然以前的工作表明，介质噪声是由位单元中的反转域引起的，但我们的时域噪声测量和使用Voronoi单元的新模型表明了另一个噪声来源：由有限的磁簇大小引起的过渡不规则性的噪声源。
In perpendicular magnetic recording, medium noise is one of the crucial issues limiting the attainable density. The purpose of the reported work was to find a guiding principle for reducing the medium noise. Although previous work suggested that the media noise is caused by reversed domains in the bit cell, our time-domain noise measurements and a novel model using Voronoi cells suggest another noise origin: a noise source of transition irregularity caused by finite magnetic cluster size.
