    摘要： 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.

    摘要： A control apparatus includes: a target value obtaining unit obtaining a total target value of power to be discharged from storage batteries; an SOH obtaining unit obtain information on a state of health for each of the storage batteries; a charge control unit determining how the power of the total target value is divided among and discharged from each of the storage battery. The charge control unit (i) compares the state of health of a first storage battery and the state of health of a second storage battery, and, in the case where the state of health of the second storage battery is higher than the state of health of the first storage battery, (ii) discharges from the second storage battery second power lower than first power which is discharged from the first storage battery.
