Abstract

We investigated the effect of an additional readout layer in TbFeCo-based bilayer media on the magneto-optical (MO) recording characteristics, by conducting experiments and calculations based on the Huth formula. The bilayer medium with an appropriate readout layer can have equivalent recording characteristics to those of a monolayer one. The designed bilayer medium showed sufficient performance for high-density MO recording, providing a sufficiently strong stray field for magneto-resistive detection. On the other hand, a monolayer medium with large magnetization resulted in poor recording performance due to its self-demagnetizing field. By comparing the recording characteristics, the guidelines for designing the bilayer structure were clarified.
