  • Patent number: 5245597
    Abstract: Disclosed are a method and a device for correcting a track deviation by the deviation of a disc through a fine seek operation that operates a tracking actuator in a coarse seek stage of an optical disc drive wherein a track cross signal of the disc is detected in the optical pick up during the course seek operation and at the same time by using an optical encoder and a linear scale which are installed separately, a scale cross signal of the linear scale is detected and the actuator is driven by a signal resulting from comparing both the signals. At the stage of the travel of the optical pick up, the track deviation of the disk is corrected, and accordingly the relative speed between the light spot and the track at a seek direction becomes small to facilitate the control of the actuator and not to be necessary for lowering a speed of the VCM used in the coarse seek in order to lower the relative speed.
