Exchange-coupled Composite (ECC) media have attracted a great deal of attention as a potential solution to the tri-lemma between the signal-to-noise (SNR), thermal fluctuations, and the writability of recording media. Several methods have been proposed to systematically design ECC media, taking into account the above-mentioned three issues. A method of evaluating the thermal stability of thin-film media, however, has not yet been established. Monte Carlo methods have been widely used to evaluate to long-term thermal decay, but their application is doubtful to strong exchange-coupled systems such as ECC media. The Langevin method is also limited to very short-term thermal decay. In this paper, we propose a simple method of evaluating thermal decay that combines an analytical method with Langevin calculations.
