A thin reflective layer (4) of a corrosion-resistant metallic material such as an alloy of Fe, Ni, and Co is deposited on the disc substrate over the pattern (3) of pits and lands. The optical disc (1) is relatively inexpensive to manufacture as no protective layer is deposited on the reflective layer (4) and is also highly resistant to aging because the reflective layer (4) is made of a corrosion-resistant metallic material.

Abstract: A recording medium having a reflective layer (6) on a transparent support (1) can be obtained by physical development of a layer of physical development nuclei (2) in the presence of metal ions. The ions can for instance migrate from a colloid layer of a metal salt (6). The association of developed nuclei, after physical development, results in a reflective layer with metal atoms obtained by reducing the metal ions, whose reflectivity is reduced on irradiation through the transparent support. The manufacture of such recording media does not require vacuum system.
