The flash temperatures which can occur at a head-disk interface are simulated with a model which permits the two contacting surfaces to be of comparable roughness and recognizes the thermally distinct overcoat on the disk. The model is fairly readily implemented, as is demonstrated by using it to generate some representative statistics for the heat partition and temperature distribution at an interface.
