发明名称 Optical disc device and controlling method thereof
摘要 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.

主权项 1. An optical disc device comprising: a pickup; a plurality of driving mechanisms, wherein one of the driving mechanisms drives the pickup; and a driving controlling portion that applies an initial driving voltage to one of the driving mechanisms 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, wherein after the specific time interval has elapsed, the driving controlling portion applies, to the one of the driving mechanisms, 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, and wherein the plurality of the driving mechanisms comprises at least two types of driving loads, and the voltage amplitude and the driving frequency of the initial driving voltage are a voltage amplitude and driving frequency able to drive the one of the driving mechanisms having the largest driving load from among the plurality of driving mechanisms.
