Abstract
A heat-assisted magnetic recording (HAMR) medium having improved signal-to-noise ratio capabilities includes a high-temperature exchange break layer (EBL) inserted between magnetic recording layers, where the high-temperature exchange break layer material is capable of maintaining its chemical properties at temperatures exceeding 300° C. The high-temperature EBL may include a non-metallic compound including at least one of an oxide, a carbide, and a nitride.
