    Abstract: Sub-information necessary for reproduction of main information is recorded on an optical disc without deterioration of reading accuracy of the main information, so that illegal reproduction is prevented. After a concave and convex mark (MK) synchronizing with integer times a channel bit length is formed on optical disc (1) in accordance with modulated main information, a reflective film (IL) is formed on the concave and convex mark (MK). After the optical disc (1) is molded, a continuous or intermittent laser light, which has an interval that is longer than the longest mark in the concave and convex mark (MK) and is synchronous with integer times the channel bit length, is irradiated to the reflective film (IL) which, in turn, changes its chemical characteristic to form a recordable mark, so that the sub-information necessary for reproduction of the main information is recorded in a superimposition manner.

    Abstract: It is possible to provide a safe and user-friendly authentication system for authenticating an object required in various conditions. The authentication system (900) includes a first authentication information transmission device (901) having first authentication information, a second authentication information transmission unit (904) having second authentication information, and an authentication unit (905) for authenticating a user or user’s right. The second authentication information transmission unit (904) transmits second authentication information only while it receives the first authentication information transmitted from the first authentication information transmission device (901). The authentication unit (905) receives the second authentication information transmitted from the second authentication information transmission unit (904) and authenticates a user or user’s right according to the second authentication information.
