Abstract
Various magnetic stack embodiments may be constructed with a soft magnetic underlayer (SUL) having a first thickness disposed between a substrate and a magnetic recording layer. A heatsink may have a second thickness and be disposed between the SUL and the magnetic recording layer. The first and second thicknesses may each be tuned to provide predetermined thermal conductivity and magnetic permeability throughout the data media.
