    摘要： 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.

    摘要： A recording power determination method for determining a recording power of an optical beam for recording data on an information storage medium includes the steps of recording test data on the information storage medium at a plurality of test recording powers; reading the test data recorded at each test recording power, generating a signal, and measuring a modulation factor of the signal corresponding to each test recording power; calculating a product of an n'th power of each test recording power and the corresponding modulation factor, thereby obtaining a plurality of products corresponding to the plurality of test recording powers, where n is a value of exponent and is a real number other than 1; calculating a first recording power based on the correlation between the plurality of test recording powers and the plurality of products; and calculating the recording power based on the first recording power.

    摘要： An optical disc device is provided with an optical pickup (6), which has a light source (23) which emits an optical beam (21) for irradiating an optical disc (100), at least one objective lens (22) for focusing the optical beam (21), and an actuator which shifts the objective lens (22) in a direction vertical to the optical disc (100); a transfer table (11) for transferring the optical pickup (6) in a disc diameter direction; a rim detecting means (30) for detecting that an irradiation position of the optical beam (21) is over an edge section of the optical disc (100), in the case of shifting the optical pickup (6) from an inner circumference side to an outer circumference side of the disc for seek operation; and a control means (40) which shifts the objective lens (22) in a direction to be away from the optical disc (100) by the actuator when the irradiation position of the optical beam (21) is detected over the edge section of the optical disc (100), and shifts the optical pickup (6) to the disc inner circumference side by the transfer table (11).
