采用磁打印记录和MFM图像的方法，研究了记录场方向对堆叠介质过渡噪声的影响。随着从垂直方向施加的场角的增加，记录介质的过渡区域中沿跨磁道方向的杂散场波动和记录介质过渡位置的色散减小。这表明，跃迁噪声随着记录场的面内分量的增加而减小。另一方面，在过渡区中，无论外场方向如何，对应于杂散场起伏周期的一半的磁畴尺寸都固定在50 nm附近。
Influence of recording filed direction on transition noise of stacked media was investigated by using magnetic printing for recording and MFM images. Stray field fluctuation along the cross-track direction in the transition area and dispersion of the transition position of the recorded medium decreased as the applied field angle increased from the perpendicular direction. This shows that the transition noise decreases with increasing in-plane component of the recording filed. On the other hand, in the transition area domain size which corresponds to half of the period of the stray field fluctuation was fixed near 50 nm regardless of the applied field direction.
