摘要： An optical disk apparatus includes an objective-lens for converging light on a recording surface of an optical disk, and an objective-lens driving device for driving the objective-lens in a focusing direction and a tracking direction. The objective-lens driving device includes a focusing coil having four edges to enclose the objective-lens, and two pairs of permanent magnets. The two pairs of permanent magnets are arranged so that polarities thereof become identical to sides of focusing coil, wherein one pair of the permanent magnets is arranged opposed to an edge of the focusing coil, and an other pair of the permanent magnets is arranged opposed to an edge opposite to the edge of the focusing coil. An interval between two magnets constituting the one pair of permanent magnets is narrower than an interval between two magnets constituting the other pair of permanent magnets.

摘要： An objective-lens driving apparatus includes permanent magnets on both ends of the movable unit, simultaneously, on the other side of the movable unit parallel to the tracking direction, also a permanent magnet at a position closer to the center of the movable unit. This configuration makes it possible to reduce each moment generated at each of a focusing coil and a tracking coil when an objective lens is displaced.

摘要： An aspect of the invention provides an optical pickup in which an optical axis is not displaced even if ambient temperature is changed. The optical pickup of the invention has an optical unit and an optical pickup case. The optical unit has a lens member having an optical axis, and the optical axis of the lens member is offset to one side from the center of the optical unit. The optical pickup case holds the optical unit from both sides. A thermal expansion amount of the optical unit is absorbed by compression amounts of a first adhesive and a second adhesive such that the optical axis of the lens member is not displaced when the optical unit is thermal expanded.
