Metal alloy heatsink films for magnetic recording media are disclosed. The
metal alloy heatsink films possess both high thermal conductivity and
improved mechanical properties such as relatively high hardness. The
metal alloy heatsink films also have controlled microstructures which are
compatible with subsequently deposited crystalline magnetic recording
layers. The films may comprise single phase CuZr or AgPd alloys having a
selected crystal structure and orientation. The combination of high
thermal conductivity, good mechanical properties and controlled
microstructures makes the metal alloy heatsink films suitable for various
applications including heat assisted magnetic recording systems.
