We have prepared high performance TbFeCo magneto-optical recording media by coevaporation. A carrier-to-noise ratio (CNR) of about 60 dB, measured with a 30-kHz slot bandwidth, was obtained and a CNR was limited mainly by shot noise. It was found that the threshold laser power in these media linearly increased with a slope of 0.3 mW/kOe as the coercivity increased.
