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.

Abstract: A data media may generally be configured in accordance with various embodiments with contactingly adjacent first and second heatsink layers that are tuned with a common crystallographic orientation and with different thermal conductivities to provide a predetermined thermal gradient. The data media may further be configured with a recording layer formed with the common crystallographic orientation adjacent the first and second heatsink layers.
