ABSTRACT:
A magnetooptical recording medium capable of performing an over-write operation by only modulating an intensity of a light beam without modulating a direction of a bias field is known. This invention provides a multilayered medium which has an advantage of a large margin for an initial field Hini. for initializing the medium, and can stably perform an over-write operation, or which can increase a beam intensity in a reproduction mode to attain a high C/N ratio.
