In the first part of the paper, we compare the predictions of our earlier theoretical work on the signal-to-noise ratio for magneto-optic read-out with experimental measurements. We then examine how the thermal response of the medium can be tailored to the light level available for recording to further enhance the SNR. In the second part, we examine theoretically the writing and erasure processes. We calculate the various contributions to the energy of formation of a domain during a typical writing cycle under an applied field and obtain some design constraints on both the medium and system that are required to ensure single domain formation in writing and good reversibility in erasure.
