摘要： In an objective lens driving means of an optical pickup, the accuracy of the boundary position of magnets is improved, the generation of angular moment through coils is suppressed, and the inclination of the objective lens is reduced. An optical pickup for reading or writing information on an optical disc using an objective lens includes a lens holder for holding an objective lens, three magnets disposed facing to each of the two sides of the lens holder that are parallel to the focusing direction and the tracking direction, and a yoke for mounting these magnets. The yoke includes a central yoke surface for mounting the central one of the three magnets, and outer yoke surfaces for mounting the outer two of the three magnets. A step is formed between the central yoke surface and each of the outer yoke surfaces.

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： 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 means 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.
