Abstract :
Heat assisted magnetic recording (HAMR) was initially proposed in the 1990´s to achieve storage densities not limited by superparamagnetism. The key to HAMR has been to find an efficient near field transducer that can operate with a nearby magnetic recording pole. An integrated HAMR head has now been demonstrated which can record at a track width of 50 nm and an areal density of ~240 Gb/in2 on high coercivity FePt media.
