Energy-assisted magnetic recording (EAMR) is a disk drive recording technology which use energy (microwaves - MAMR or heat - HAMR) to increase the areal density (a higher BPI value) during writing operations by improving writability. [1][2][3] To lower the resistance of the storage medium for having its polarity changed (high coercivity), energy is applied on the recording head: electrical current in ePMR (energy-assisted perpendicular magnetic recording), a laser source for heating temporarily the disk material (HAMR), a spin-torque oscillator (STO) for microwaves (MAMR).[4][5][2][6][7]
