An analysis of readout signal and noise generation is presented for a magneto-optical data storage system which uses a single laser beam for both Curie-point thermal writing and Faraday readout of magneto-optical films. The analysis is applied to a cryogenic beam addressable file model which utilizes GaAs injection lasers and doped EuO film.
