COMPOSITE MAGNETO-OPTICAL INFORMATION RECORDING MEDIA

摘要

A composite magneto-optical information recording medium comprising a substrate (1) and a composite magneto-optical recording layer deposited on said substrate. The composite magneto-optical recording layer comprises a magneto-optical layer (2), a metallic layer (3) and an electron transition layer (4) which exhibits transition of electrons in a wave length range of a laser beam used for recording and/or regenerating information, the three layers being layered successively in this order so that said laser beam (L) impinges on a side of said magneto-optical layer (2).
