Abstract: Various aspects of this disclosure provide a recording medium for heat-assisted-magnetic-recording (HAMR). The recording medium may include a substrate. The recording medium may further include a recording layer. The recording medium may also include a thermal control layer between the recording layer and the substrate. The thermal control layer may have a thermal conductivity that increases with increasing temperature.
