• the sample surface, has no impact on the recorded magnetic features – thus suggesting full compatibility with NFT-HAMR. Keywords: laser absorption; laser heating; thermally assisted magnetic recording; Introduction Heat-assisted magnetic recording (HAMR) is widely considered the most promising

• stable data storage on hard disk drives (HDDs) for at least another decade, and in combination with technologies like bit-patterned media, perhaps far beyond [3][4][5]. In HAMR (also called: thermally assisted magnetic recording) the recording medium is locally heated to lower the required magnetic field
