ملخص
The areal storage density of magneto-optical (MO) recording can be increased with the magnetically induced super-resolution (MSR) readout technique. In the present work, the effect of laser energy, disk velocity, and cooling time on the magnetic reversal processes in the MSR technique is discussed. The magnetization distribution and the temperature profile within MO multilayer media are investigated based on a micromagnetic model using a heat conduction theory. The magnetization of the readout layer, initially with in-plane magnetic anisotropy, can be switched perpendicularly to the film plane in a small temperature region. This magnetic reorientation depends on the strength of the exchange coupling between different layers. The correlation between this exchange coupling and dynamic parameters is discussed.
