    • In an optical disc reproducing apparatus, when an amount of light received by an optical pick-up varies or leakage light enters a light receiving portion due to the tilt of the optical pick-up or the like, a tracking control signal generation circuit adds an offset in accordance with a control value outputted from a tracking actuator controller to an output of a tracking servo filter. As a result, a tracking servo pull-in operation is performed in a state where the optical pick-up is forcibly tilted. The direction in which the optical pick-up mentioned above is forcibly tilted is determined from the result of, e.g., measuring the duty ratio of a DPD off-track signal. Therefore, a reproduction signal, a focus error signal, and a tracking error signal are correctly generated without providing a tilt mechanism in the optical pick-up.
    • 在光盘重放装置中,当光拾取器所接收的光量变化或由于光学拾取器等的倾斜而使光入射到光接收部分时,跟踪控制信号发生电路将 根据从跟踪致动器控制器输出的控制值到跟踪伺服滤波器的输出而偏移。 结果,在光学拾取器被强制倾斜的状态下执行跟踪伺服拉入操作。 根据例如测量DPD偏离轨迹信号的占空比的结果,确定上述光学拾取器强制倾斜的方向。 因此,在光学拾取器中不设置倾斜机构的情况下,正确地产生再现信号,聚焦误差信号和跟踪误差信号。
