研究了具有不同槽深的周期性织构磁记录介质。从一系列的MFM图像的开关场和开关场分布的变化的空间地图。当反向场沿着纹理施加时，形成长的反向链，并由纹理凹槽引导。大多数晶粒在相对较小的外加磁场范围内发生转变。对于横向于织构施加的场，反转的短链沿着织构化沟槽形成，并且切换在更宽的施加场范围内发生。
Periodically textured magnetic recording media with different groove depths are investigated. A spatial map of the variation in the switching field and switching field distribution are derived from a series of MFM images. When the reversing field is applied along the texture, long chains of reversal are formed and channeled by the texture grooves. Most grains switch within a relatively small range of applied fields. For fields applied transverse to the texture, short chains of reversal form along the textured grooves, and switching occurs over a broader applied field range.
