Abstract:
An optical storage medium has a substrate and a cover layer that allows light to pass therethrough in recording or reproduction. Provided between the substrate and the cover layer are at least a reflective film, a first dielectric film, a recording film, and a second dielectric film formed in this order from the substrate side. Provided further between the second dielectric film and the cover layer is a damp-proof film that is at least partially an amorphous film and contains at least an indium oxide.
