Output decay by thermal relaxation in perpendicular double-layered media is studied by numerical calculation and experiments. In addition some Influences due to a single pole head are pointed out We suggest that If these influences could be avoided, thermal relaxation In perpendicular magnetic recording would be much smaller than reported so far. High recording density and low noise is passible with relatively small particles, even at large fllm thickness In perpendicular magnetic recording.
