  • Method and apparatus for adjusting reproduction speed of optical disk
    Patent number: 6791925
    Abstract: The present invention relates to an apparatus and method for adjusting the reproduction speed of an optical disk, and more particularly, to a method for adjusting the reproduction speed of an optical disk which is capable of selectively adjusting the reproduction speed to a lower speed in advance only with respect to an abnormal regional section of the optical disk inserted into a driver, and normally reproducing a recording signal on the optical disk at the original high speed with respect to sections excepting for the abnormal regional section. Thus, there is an effect of reproducing data at a high speed even if the state of the optical disk is bad. In addition, a delayed reproduction time delayed can be removed by gradually reducing the reproduction speed of the optical disk.
