Abstract Thermal decay in magnetic recording media increases with time, consequently decreasing the signal-to-noise ratio. A recently developed scaling technique, based on the equivalence of time and temperature within micromagnetics, has been used to predict bit decay over long time scales. An ideal square-wave field is used to record bits in thin film magnetic recording media. Comparison of bit thermal stability for longitudinal and perpendicular thin film media with similar K{sub u}V/kT is carried out at recording densities from 50 to 400 Gbit/in.{sup 2}. Bit decay in a Co/Pd superlattice film at {similar_to}100Gbit/in.{sup 2} is also studied. {copyright} 2001 American Institute of Physics.
