    • The present invention provides a deficiency detecting apparatus that can accurately detect dusts and deficiencies on an optical disk even when an emitting power of a laser light source changes. The deficiency detecting apparatus is provided with a deficiency detecting section for detecting deficiencies or the like on an optical disk by reflected light, and a power adjusting section for adjusting an emitting power of a laser light source to be an optimum value. The deficiency detecting section can accurately detect the deficiencies on the optical disk even when the laser power changes by comparing a threshold value, which is determined in accordance with the adjustment result of the power adjusting section, with a value in accordance with the reflected light.

    • When a focus error signal (FE signal) is detected with an astigmatic method, a track crossing component leaks into the FE signal. Another detection method for the FE signal would reduce the leaking signal, but is not applicable when the light use efficiency decreases. An optical crosstalk correction amount determination unit (1000) determines a correction amount to correct an output of a tracking error detection unit (120) based on optical crosstalk from a TE signal to an FE signal occurring in reflection light from an optical disc (102) when a spot crosses a track. An output of the tracking error detection unit (120) is multiplied by the determined correction amount, and added to an output of the focus error detection unit (118). A focus control unit (138) executes focus control based on the addition result. This effectively reduces a TE signal component that leaks into the FE signal due to optical crosstalk.
    • 当利用散光法检测到聚焦误差信号(FE信号)时,轨迹交叉分量泄漏到FE信号中。 FE信号的另一种检测方法将减少泄漏信号,但是当光使用效率降低时不适用。 光串扰校正量确定单元(1000)基于从TE信号到来自光盘(102)的反射光中发生的FE信号的光串扰确定校正跟踪误差检测单元(120)的输出的校正量, 当一个点穿过一条轨道。 将跟踪误差检测单元(120)的输出乘以所确定的校正量,并将其相加到聚焦误差检测单元(118)的输出。 聚焦控制单元(138)基于相加结果执行聚焦控制。 这有效地减少了由于光串扰而泄漏到FE信号中的TE信号分量。
