在垂直记录介质的模拟中，相邻单元之间的交换耦合被随机破坏以提供畴壁钉扎位点。这种钉扎位置的引入可以通过降低介质对杂散场的敏感性并因此减少记录数据的不希望的擦除来提高强交换耦合介质的信噪比。
In a simulation of perpendicular recording media, the exchange coupling between adjacent cells was broken at random to provide domain wail pinning sites. The introduction of such pinning sites can improve the signal/noise ratio of strongly exchange coupled media by reducing the susceptibility of the media to stray fields and thus reducing unwanted erasure of recorded data.
