摘要： An optical disk drive and a digital servo method for the optical disk drive includes controlling functions of the optical disk drive with a microprocessor. Low-pass filtered and gain-adjusted versions of photodetector output signals resulting from an illumination of an optical disk are received. Versions of the photodetector signals are digitized to produce digital signals. A focus control signal is determined through at least one servo algorithm executed by a digital signal processor based on a focus error determined from the digital signals. Alternatively, a tracking control signal is determined through at least one servo algorithm executed by the digital signal processor based on a tracking error determined from the digital signals. The digital signal processor has a specialized structure and arrangement for processing digital signals at a higher speed than the microprocessor.

摘要： An optical disk drive and a digital servo method for the optical disk drive includes controlling functions of the optical disk drive with a microprocessor. Low-pass filtered and gain adjusted versions of individual photodetector output signals resulting from an illumination of an optical disk are received. Versions of the individual photodetector output signals are digitized to produce digital signals. A focus control signal and/or a tracking control signal is determined through at least one servo algorithm executed by a digital signal processor based on a focus error and/or tracking error, respectively, determined from the digital signals. The digital signal processor is an integrated circuit structured and arranged for manipulation of digital signals in accordance with programmed commands, and in a manner that operates faster than the microprocessor.
