Per­pen­dic­u­lar record­ing (or Per­pen­dic­u­lar Mag­net­ic Record­ing, PMR) is a recently imple­men­ted tech­no­logy for data record­ing on hard disk “The main chal­lenge in design­ing mag­net­ic inform­a­tion stor­age media is to retain the mag­net­iz­a­tion of the medi­um des­pite thermal fluc­tu­ations caused by the super­para­mag­net­ic lim­it. If the thermal energy is too high, there may be enough energy to reverse the mag­net­iz­a­tion in a…
