Abstract
According to embodiments of the present invention, a method for manufacturing a recording medium for heat-assisted-magnetic-recording (HAMR) is provided. The method includes forming an underlayer on a substrate, the underlayer including a precursor material, epitaxially depositing an interlayer on the underlayer, forming a recording layer over the interlayer, and converting the precursor material to a converted material having a thermal conductivity that is higher than a thermal conductivity of the recording layer. According to further embodiments of the present invention, another method for manufacturing a recording medium for heat-assisted-magnetic-recording (HAMR) and a recording medium for heat-assisted-magnetic-recording (HAMR) are also provided.
