摘要： In order to achieve further cost reduction while the package size of an optical pickup having two objective lenses and the restriction on the disposition of the two objective lenses are maintained, an optical system for laser light emitted from a red/infrared dual-wavelength laser diode is disposed such that a parallel plate beam splitter is disposed to be inclined with respect to the optical axis of focused light of the laser light reflected by an optical disk and the optical axis of the laser light between a rising mirror and the parallel plate beam splitter is inclined from the signal track direction of the optical disk. The laser light to which astigmatism is given by transmission through the parallel plate beam splitter is caused to be directly incident on a light detector without passing through an astigmatism adjustment optical element.

摘要： PROBLEM TO BE SOLVED: To improve environment resistance characteristics of an optical pickup by miniaturizing a collimator lens moving mechanism and reinforcing an optical pickup housing in a space created thereby.SOLUTION: The optical pickup including a lens moving mechanism comprises: a lens; a lens holder for holding the lens; a guide member for guiding the lens holder; a lead screw having a screw groove; a motor for rotating the lead screw; a rack gear including a body part fixed to the lens holder and a claw part fitted in the screw groove of the lead screw. An arm for connecting the body part and the claw part of the rack gear is formed such that a cross-sectional shape of a plane perpendicular to the rotary axis direction of the lead screw becomes a convex shape, a concave shape and a wave shape. The width direction of the rack gear can be shortened by an improvement in torsional rigidity of the rack gear so as to miniaturize the collimator lens moving mechanism.
