摘要： An optical disk has a first substrate having a recording layer thereon, information to be recorded on the recording layer being reproducible with irradiation of a laser beam, a reflective layer formed on the recording layer, and a second transparent substrate, the laser beam being incident to the second substrate in reproduction. The first and the second substrates are bonded to each other by a bonding layer via the reflective layer. The bonding layer includes ultraviolet-hardened resin and at least one type of photochromic dye that is stable against the laser beam. In another type, the first substrate maybe transparent. Instead of the second substrate, this type has a hardcoat layer formed on a surface of the first substrate opposite to another surface thereof having the recording layer thereon, the laser beam being incident to the hardcoat layer in reproduction. The hardcoat layer includes ultraviolet-hardened resin and at least one type of photochromic dye that is stable against the laser beam.

摘要： A method for making an otical recording medium comprises providing a substrate which is encoded with information in the form of pits and/or a continuous groove beforehand at least on one side thereof, spraying a solution or dispersion of a film-forming material containing at least one organic compound having optical functionality in the form of a mist onto the encoded side of the substrate in a vacuum chamber under conditions sufficient to permit a thin film to be formed thereon in a substantially solvent-free condition, and drying the thin film. An optical recording medium obtained by the method is also described.
