  • Publication number: 20020016642
    Abstract: The disclosure is to learn a periodic disturbance along with the disk rotation and to improve track-following accuracy. The disk apparatus comprises a head, apositional signal detection section respect to the track of the medium, a feedback control section which computes a control signal for moving the head from the positional signal by a position signal detector, and a learning control section which obtains an unknown function for one disk rotation along with the periodic disturbance to the memory which is comprised of N number of memory cells by a learning algorithm as an approximate function which is approximated by the height of each block. The learning control section reads the learning result of the two memory cells at locations which are moved forward for a predetermined amount of time, and interpolates the results so as to generate the periodic disturbance compensation signal.

  • Patent number: 6341107
    Abstract: A control unit positions a laser beam toward a target track on a medium on the basis of a tracking error signal (TES) Y indicative of a positional deviation amount from a track center as a zero point on the basis of return light from the medium. A position signal correcting unit executes a correcting arithmetic operation using a non-linear function such as a quadratic polynomial, a quadratic monomial equation, or the like to the TES Y and outputs a corrected TES Z obtained by correcting detection sensitivity characteristics to desired characteristics so that a feedback is sufficiently performed when a lead-in control to the track center by the control unit is executed.
