Abstract
Thermal stability of data stored in thin film recording media is closely ti ed to signal-to-noise ratio (SNR), yet is not correlated in a simple way. I ndeed grain size strongly affects both SNR and thermal stability, but macro scopic magnetic properties as well as recording conditions are equally infl uential. This is illustrated by measurements of SNR and signal thermal deca y along with a simple model analysis. Dependence of areal density on key ma gnetic properties, under SNR and stability constraints, is formulated.
