摘要： In an optical pick-up used in common with DVD/CD and BD, when the thickness is intended to be reduced by mounting a total reflection mirror, a cavity for passing through a laser light is necessary and, since this decreases the degree of freedom for arranging tracking coils and magnets and secondary resonance caused by a magnetic thrust in the tracking direction tends to be generated, an improvement therefor is necessary. In a lens coil holder of the optical pick-up having an objective lens and tracking coil mounted thereon each of the coils is arranged such that the thrust relative to the vertical center of the suspension wires that support the lens coil holder is well balanced. For example, most of the portion of the tracking coils is situated at one height relative to the suspension wire and the tilt coil is situated at the other remaining height.

摘要： An optical pickup that can be downsized is suggested.The optical pickup includes: a collimator lens positioned on an optical path of a laser beam between a laser diode and an objective lens; and a collimator lens moving unit for moving the collimator lens along the optical path of the laser beam in a direction approaching the objective lens or a direction moving away from the objective lens; wherein a reference position of the collimator lens where the laser beam which has transmitted the collimator lens becomes parallel rays is set at an end or an approximately end of a movable range of the collimator lens that is closest to the objective lens; and wherein the objective lens is formed so that spherical aberration occurring in the laser beam which is made to converge on an outermost recording layer of the multilayered optical disc that is closest to the objective lens can be cancelled by spherical aberration occurring in the laser beam entering the objective lens through the collimator lens located at the reference position.

摘要： An optical pickup device includes a hosing having three walls connected together whose horizontal cross-section is substantially U-shaped. A first wall supports one end of a shaft, a second wall facing the first wall supports the other end of the shaft and a third wall connects the first and second walls. A lubricant tray is surrounded by the three walls and the shaft. By the shaft being attached to an end side surface of the lubricant tray, the shaft can be integrally formed with the housing. A radius of curvature or an angle formed on a horizontal cross-section of the three walls is larger than a radius of curvature or an angle formed between one of the three walls and the lubricant tray.
