摘要： An information reproducing apparatus comprises an optical head that reads the lengths and arrangement of recording marks recorded on an optical disc and outputs RF signals, a PRML decoder that decodes binary data based on the RF signals output from the optical head, a short mark asymmetry measuring unit that measures an asymmetry in an RF signal of the RF signals output from the optical head that corresponds to a 2T mark or shortest recording mark, and an RF signal offset unit that offsets the RF signals so as to remove the asymmetry in the RF signal corresponding to the 2T mark based on the measurement by the short mark asymmetry measuring unit. The PRML decoder decodes the binary data based on the RF signals offset by the RF signal offset unit. The information reproducing apparatus can provide improved performance in reproduction of information recorded on an optical disc.

摘要： In an optical disc drive, a laser light source emits a laser beam having an intensity changeable with the amount of drive current supplied. A first photodetector receives the laser beam reflected from an optical disc, thereby generating a readout signal. A second photodetector receives the laser beam, generates an electric signal representing the power of the laser beam received, and outputs the electric signal as a light quantity detection signal. A feedback control loop compares the level of the light quantity detection signal with a predetermined target value and regulates the drive current such that the level of the light quantity detection signal approaches the target value. In reading data from the optical disc, the target value is changed so as to compensate for a variation of the sensitivity of the second photodetector, thereby controlling the power of the laser beam emitted from the laser light source.
