摘要： PROBLEM TO BE SOLVED: To generate a light reception signal required for tracking control without being affected by interlayer stray light. SOLUTION: An optical disk device 190 calculates a tracking error signal STE3 according to expression (12). In expression (12), an optical pickup 197 removes, when a stray light layer distance dn is within a stray light layer distance range dh1, a rapidly increasing stray light component from a push-pull component by utilizing values obtained from stray light reception regions D52P and D52Q which are substantially proportional to the stray light component included in the push-pull component. As a result, even when the stray light layer distance dn is small and a lens shift occurs, the optical disk device 190 generates the tracking error signal STE3 having no influence of stray light patterns W formed from interlayer stray light beams LN from a plurality of recording layers Y, thereby achieving tracking control with high accuracy.

摘要： PROBLEM TO BE SOLVED: To provide a technique for removing astigmatism and accurately recording and reproducing information without redundancy in an optical disk device which uses a rising prism and includes an optical pickup device for dynamically correcting astigmatism. SOLUTION: A correction amount of spherical aberration is adaptively controlled by changing a divergent angle or a convergent angle of laser light made incident to the rising prism by moving a collimator lens 34a along the optical axis. However, the astigmatism occurs due to the rising prism 36. Moreover, this astigmatism changes according to the changes in the divergent angle or the convergent angle of the laser light. Therefore, the astigmatism caused by the rising prism 36 is removed by controlling an astigmatism correcting element 35 according to the changes in the divergent angle or the convergent angle of such laser light.
