A scanning laser microscope has been designed to observe the dynamic behaviour of domain switching during the thermo-magnetic write process and the subsequent magnetisation state (domain orientation) in thin-films and devices. It will also be used to write to magneto-optic (MO) disk material thermo-magnetically prior to imaging. Images are derived from the longitudinal and polar magneto-optic Kerr effects, which are wavelength dependent, using the appropriate laser wavelength. In this paper the different configurations for imaging are described, and some initial images are presented
