ABSTRACT:
A storage medium comprising a multilayer system with at least one magnetic layer, of magneto-optical storage material, and at least one reflector layer, with an index of refraction n<1, which is at least as thick as one of the magnetic layers. The maximum thickness of each of the magnetic layers is inversely proportional to its absorption coefficient, K. In the magneto-optical multilayer system of the present invention, a large Kerr angle O.sub.K is obtained.
