  • Optical disc device and controlling method thereof
    Patent number: 8923107
    Abstract: An optical disc device includes a pickup, a driving mechanism that drives the pickup, and a driving controlling portion that applies an initial driving voltage to the driving mechanism over a specific time interval up until the pickup arrives at an outermost position on an outer peripheral side, the initial driving voltage causing the pickup to arrive at the outermost position. After the specific time interval has elapsed, the driving controlling portion applies, to the driving mechanism, an adjustment driving voltage of a voltage amplitude less than a voltage amplitude of the initial driving voltage or a driving frequency less than a driving frequency of the initial driving voltage.
    Type: Grant
