Abstract
Media thermal stability is characterized by using spin-stand tests for both signal and signal-to-noise ratio (SNR) decay. Agreement is shown between vibrating sample magnetometer (VSM) and spin-stand evaluations of the thermal decay rate dependence on linear density. For an equalized system, there is linear correlation between measured SNR and signal decay rates. Equalization to targets with DC content will result in higher decay
