  • Patent number: 8169260
    Abstract: An amplifier circuit performs a characteristic correction process and a smooth curvilinear process on an input signal before being subjected to amplification. The characteristic correction process is a frequency characteristic process, which is performed on the input signal so as to produce a processed signal (Vp). Either the input signal or the processed signal, or the mixture of these signals is subjected to the smooth curvilinear process whose start point is designated by a state variation of amplification (VxTyp). Alternatively it is subjected to a gain decrement process instead of the smooth curvilinear process when the state variation of amplification is less than a default value (VxTHD). Thus, it is possible to prevent clipping from occurring in the amplified output signal while maintaining an adequate power.

  • Patent number: 8018824
    Abstract: An optical pickup is disposed which irradiates a laser beam onto an optical disc where a guide groove having characteristics of thermal interference (heat discoloration) is spirally formed. The optical pickup irradiates the laser beam along the guide groove to conduct one of data recording in which pits indicating a data length are formed, and visible-image formation in which a part of the optical disc is discolored. The laser beam irradiation position is controlled so that the data recording is conducted with starting from the inner peripheral side of the optical disc, and the visible-image formation is conducted with starting from the outer peripheral side of the optical disc.
