Abstract
We characterize a method of heat-assisted magnetic recording (HAMR), which may be applied for high-density probe storage system. The magnetic recording medium is a CoNi/Pt multilayered film, suitable for perpendicular recording. The heating source is the field emission current from a scanning tunneling microscopy (STM) tip, with pulse voltages added between the tip and the film. Writing shows a threshold voltage of 4 V. Marks with an average size of 165 nm were achieved for pulses above 4 V. A model of dynamic domain formation is applied to simulate the process of the formation of marks. The effect of domain wall forces is discussed. Simulation results agree with experiments well, without the need of taking domain wall forces into account.
