ABSTRACT:
A recording/reproduction method for recording or reproducing information using the magneto-optical recording medium, the magneto-optical recording medium comprising a first magnetic layer comprising a rare earth-transition metal alloy or a ferromagnetic material containing a magnetic transition metal, a second magnetic layer comprising a rare earth-transition metal alloy, a third magnetic layer comprising a rare earth-transition metal alloy, a fourth magnetic layer comprising a rare earth-transition metal alloy, a fifth magnetic layer comprising a rare earth-transition metal alloy, and a sixth magnetic layer comprising a rare earth-transition metal alloy, the second to sixth magnetic layers being stacked in this order on the first magnetic layer, adjacent layers of the second to sixth magnetic layers being coupled by an exchange force thereof.
