Abstract
In this paper, the real time thermal effect of the heat-assisted magnetic recording (HAMR) on the slider is investigated with the HAMR platform. The net temperature rises of the slider caused by laser absorption and heat radiation of the locally heated recording magnetic disk are studied by monitoring the calibrated read sensor resistances in different rotation speeds. The maximum slider temperature increase of about
3.5
°
C
caused by the locally heated recording disk is obtained when the media net temperature increase is
85
°
C
at

rpm
rotation speed. A higher temperature case is also discussed.
