Measurement of Transient Temperature during Thermomagnetic Writing in MO Recording Media

Abstract

Real-time Kerr contrast images produced by a time-resolved microscope were used to derive transient temperature during thermomagnetic writing. Temperature profiles in magneto-optical films during TM writing were measured, and Curie diameter could be derived. Comparison between numerical and experimental methods indicates that accurate values of thermal and material parameters, and the nature of recording media are critical of obtaining transient temperature profiles. © 1992 IEEE
