Patent ID: 8391111

Claim:
An optical pickup control circuit comprising an adding portion that adds a tracking driving signal, generated by a tracking driving section, for moving an objective lens, provided to face a discoid optical information recording medium, in a tracking direction of the corresponding optical information recording medium, to a tilt driving signal, generated by a tilt driving section for moving the corresponding objective lens in a tilt direction of the corresponding optical information recording medium, and supplies the added signal to a tilt actuator; further comprising a gain adjusting portion that changes a gain value of the tracking driving signal in accordance with a rotation frequency of the optical information recording medium and supplies the changed gain value to the adding portion, wherein the gain adjusting portion changes the gain value of the tracking driving signal by using coefficients of a gain and the rotation frequency of the optical information recording medium, obtained from a ratio of the difference between a first set frequency and a second set frequency to a difference between the gain values at the first and second set frequencies.
