Optical magnetic recording medium |
摘要 |
In an optical recording medium comprising a substrate and a recording layer thin film comprised of a rare earth element and a transition metal, for example, TbFeCo on the substrate, a metal thin film layer having a high magnetic permeability, for example, Permalloy is formed on the recording layer. A transparent dielectric film layer may be formed between the substrate and the recording layer thin film.
