Abstract: An actuator for an optical pickup and an optical recording and reproducing apparatus are provided to have a simple structure and maintain high sensibility. An objective lens for inputting light to an optical information storing medium is mounted in a lens holder, and the lens holder is movably connected to a base by a supporting member. A magnetic circuit independently drives the lens holder in a focusing direction, a tilt direction, and a track direction. The magnetic circuit has the first and the second focusing coils(41,42), a tilt coil(43), a pair of track coils(44,45), and 2-polarizing magnets(61,63). The first and the second focusing coils(41,42) are arranged in the track direction from the lens holder. The tilt coil(43) is laminated with the first and the second focusing coils(41,42) in the focusing direction, and is supported by the lens holder. The track coils(44,45) are supported to the lens holder, and are horizontally disposed in the track direction. The 2-polarizing magnets(61,63) generate a driving force in the focusing direction by interaction with the first and the second focusing coils(41,42), generate a driving force in the tilt direction by interaction with the tilt coil(43), and generate a driving force in the track direction by interaction with the track coils(44,45).

Abstract: An optical pickup device is provided to facilitate the control operation of a collimating lens and prevent the damage of optical parts due to error operation of the collimating lens by using a position sensing sensor for sensing a reference position of the collimating lens. An objective lens(11) concentrates an incident light on a recording surface of an optical recording medium(10). An optical detector(15) receives the light, which is concentrated on and reflected from the recording surface of the optical recording medium(10). A collimating lens(19) guides a parallel light to the objective lens(11). A driver(20) moves the collimating lens(19) in an optical axis. A position sensing sensor(30) senses a reference position of the collimating lens(19).

Abstract: An optical pickup is provided to reduce the number of components composing the optical pickup by receiving beams reflected from optical discs of mutually different two kinds or more and processing the received beams by using only a single photo detector in the optical pickup capable of interchanging the optical discs and recording/reproducing information. At least one collimating lens(71,72), formed on at least one optical path, forms a collimating beam. A photo detector(43) receives a beam inputted through at least one optical path. A sensor lens(100) generates astigmatism corresponding to a focus error in a surface of the photo detector(43). A single actuator driving unit(156) drives at least one collimating lens(71,72) and the sensor lens(100).
