摘要： An optical pickup device includes a light source for emitting light beam onto a recording medium. A lens is provided in an optical path between the light source and the recording medium. The lens converges the light beam to create a focusing spot on the recording medium. A tracking error detector receives a light beam reflected from the recording detector also receives a reflected light beam to detect a focusing error. A controller receives an output from the tracking error detector and the focusing error detector to produce a tracking error correction signal and a focusing error correction signal. A deflection angle adjuster is provided in the optical path and is responsive to the tracking error correction signal. The angle adjuster adjusts a deflection angle of the light beam. A refractive index adjuster is provided in the optical path and is responsive to the focusing error correction signal. The refractive index adjuster adjusts a refractive index of the light beam.
