Abstract :
An experimental method of measuring the distribution of thermal stability factors, KuV/kBT, in thin film hard disk drive media samples using a vibrating sample magnetometer is described. The measurement results indicate that energy barrier distribution width is less than intrinsic physical volume distribution
