Abstract
We studied a method of heat-assisted magnetic recording (HAMR). The recording mediumis a strongly coupled Co/Pt multilayered thin film, suitable for perpendicular recording.Field emission current from a scanning tunneling microscope (STM) tip is used as theheating source. Pulse voltages of 5 V were applied to the film. Experimental results showthat an average mark size of 100–120 nm was achieved, with the minimum being45 nm. Models of domain stability and dynamic domain formation are built toquantitatively explain the experimental results. They agree well with experiments. Themodels give us future directions for achieving small marks for ultra-high recordingdensity.
