Description

A method of heat-assisted magnetic recording potentially suitable for probe-based storage systems is characterized. Field emission current from a scanning tunnelling microscope tip is used as the heating source. Pulse voltages of 5 V were applied to a granular CoNi/Pt multilayered film. Experimental results show that an average mark size of 90-120 nm was achieved with the minimum of 70 nm. A model of dynamic domain formation is built to quantitatively explain the experimental results. It agrees with experiments. Based on this model, we will be able to figure out the proposals to achieve small marks for ultra-high recording density
