摘要： The present invention provides an object lens actuator in which a tilt of an object lens due to a change of an ambient temperature is inhibited even when a metal member is attached to a resin based securing part. It is desirable to improve quality of writing and playing in a disc drive using the object lens actuator. This is achieved by coupling a metal member having a flat portion and bent portions to a securing part near top ends of the bent portions. The flat portion has a normal in the focusing direction. The bent portions extend in the focusing direction from the respective ends of the flat portion in the tracking direction. The securing part has an opening therethrough in the focusing direction, and in the opening, the metal member and the securing part may be coupled between each outermost two support members in the focusing direction.

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.

摘要： This invention aims at reducing a rolling moment generated in coils mounted to lens holder side face without losing drive forces in a focusing direction and tracking direction in an objective lens drive of an optical pickup device. By shifting a coil line portion near the objective lens of two coil line portions substantially parallel to the tracking direction of the first coil in a direction departing from a lens optical axis, increase and decrease in drive forces generated in right and left first coils when the lens holder is moved in the tracking direction cancel each other so as to eliminate imbalance between the right and left drive forces.

The remaining holders have focus coils that are wound therearound. Alternatively, the lens-coil holder is divided into two holders, one of which has on its sides wire-winding protrusions for wiring wire rods therearound to make tracking coils. The remaining holder holds an optical lens thereon and has focus coils that are wound therearound. The lens-coil holder has a cavity for letting pass through a laser beam emitted in parallel to an optical disc surface.

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： In a background-art optical disk drive, it is necessary to improve acceleration generated in an objective lens driving device in order to make an objective lens track a disk rotating at a high speed. This can be achieved either by increasing a thrust force acting on a movable body including the objective lens or by making the movable body lighter in weight. One method for increasing the thrust force is to make permanent magnets larger or use permanent magnets having a large magnetic force. However, this leads to such a problem that the unit becomes larger in size or higher in cost. In order to solve the foregoing problem, an inner yoke is disposed around a beam of light and inside the movable body of the objective lens driving device. Alternatively, an inner yoke having at least two sides substantially parallel with the radial direction of the disk and at least two sides substantially perpendicular thereto is disposed inside the movable body.
