摘要：An optical information processing method and apparatus performs a lightirradiating and receiving step, a signal processing step, and an adjusting step of a
spherical aberration and a focus offset on the basis of shift amount of first and secondcontrol devices and a performance evaluation value. The performance evaluation valuesfor first, second, third and fourth points in an x and y coordinate system are detected, inwhich an x-coordinate is one of the shift amount of the first control device and the shiftamount of the second control device and a y-coordinate is the other, the first point,second and third points having the same y-coordinate and different x-coordinates witheach other, the fourth point being provided on a first straight line passing through thefirst point and being different from the first point.
