Abstract

A complex transverse alternating-current (ac) suspectibility [X.sub.T] technique based on magneto-optical detection is developed with sufficient sensitivity for thin film recording media. The technique is used to measure the dispersions in grain size and anisotropy field in perpendicular magnetic recording media.
