摘要：
A discrete track perpendicular magnetic recording (PMR) disk and a method of fabricating the disk are described. The PMR disk may include a heat sink layer disposed above a substrate, intermediate layers disposed above the heat sink layer, and a magnetic recording layer disposed above the intermediate layers. The magnetic recording layer may have raised and recessed areas, where a heat conductive material may be disposed within one or more of the recessed areas.
