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： 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 optical disc apparatus capable of reducing looseness vibrations resulting from a gap between a sub-guide shaft and a bearing is provided. According to an optical disc apparatus in the present invention, both ends of the sub-guide shaft are supported by being sandwiched between a pair of support parts formed in a chassis and a pair of pressing members mounted on the chassis. The support part is formed by bending a protruding portion both protruding in an inward direction of a hole from an edge of the hole of the chassis and extending along the direction perpendicular to the sub-guide shaft.

摘要： An optical pickup apparatus comprises a laser beam source to generate laser beam, and a laser driving circuit to drive the laser beam source. The laser driving circuit is connected to a flexible substrate and arranged in a groove or hole provided in the vicinity of that portion of an optical pickup housing, to which the laser beam source is fixed. The laser driving circuit is connected through a heat conduction member to an upper cover among upper and lower covers, the upper cover being close to the laser driving circuit. Thereby, heat generated from the laser driving circuit is conducted through the heat conduction member to the upper cover to be transferred outside the optical pickup apparatus while being scattered in an inplane direction of the upper cover.
