OPTICAL PICKUP HAVING AN EXCELLENT OPTICAL CHARACTERISTIC

摘要

An optical pick-up having the superior optical characteristics is provided to suppress the generation of unnecessary resonance, caused by a change in displacement of a movable frame body, to the minimum. A movable frame body(105) is movably supported in tracking and focusing directions through six wires(109) in relation to a fixing member(106). At the six wires, upper and lower three wires are arranged up and down in the same distance. The wires are separated electrically and an end of a portion of the wires is connected with a semiconductor laser(102) and a light receiving device(103) through a bonding wire(110). The property deviation of each wire is averaged in relation to horizontal/vertical movement of the movable frame body.
