摘要：

This paper reports on two thin film media alloys Co86Cr12Ta2 and Co75Ni25 which have very different noise characteristics. The magnetic microstructure of these films was observed with SEMPA. The anisotropy and the rotational hysteresis loss measurements have been made using a torque magnetometer, The distribution of anisotropy field Hk and its width dHk have also been measured, along with its different normalized values. We suggest that the observed magnetic microstructure can be directly correlated with measured readback noise and anisotropy differences. © 1990 IEEE
