IPC: G11B7/095
Filed: 2001-02-20
Abstract: PURPOSE: A method for controlling radial tilting drive of an optical pickup actuator is provided to supply power separately to focusing, tracking, and right/left radial coils, and to detect a tracking drive voltage upon radial tilting drive after tracking drive of a lens holder, so as to compensate asymmetric magnetic flux distribution with a drive voltage ratio of right and left radial tilt coils. CONSTITUTION: A tilt component of an optical disk, that is a radial tilt amount of the optical disk by a bend or instrumental run-out of the optical disk, is detected(S101). A current tracking drive voltage is detected to check asymmetric magnetic flux distribution(S102). If the current tracking drive voltage is detected, a radial drive voltage ratio for separately supplying the voltage to right and left radial coils of a lens holder is calculated(S103). And the lens holder is driven purely in a radial tilt mode, when radial tilt drive is applied to the lens holder according to the radial drive voltage ratio capable of compensating the asymmetric magnetic flux distribution(S104).
