摘要： An optical pickup device comprises a semiconductor laser that causes outgoing of laser beam used for reproduction and recording of information on an optical disk, and an objective lens that conducts the laser beam outgoing from the semiconductor laser to the optical disk. The objective lens is driven by a yoke, a focusing coil, a tracking coil, etc. These elements are accommodated in a pickup housing. First and second bearing portions supporting the pickup housing to make the same movable are attached to the pickup housing and arranged on both sides with the objective lens therebetween. The yoke is thermally connected to the first bearing portion positioned on an opposite side of the yoke to the semiconductor laser.

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.

摘要： The present invention has an object to provide an object lens actuator that reduces the amplitude of vibration of an object lens related to a torsional vibration of a lens holder and to enable a disc drive using the same to record information on a disc at high speeds. The above object has been achieved by placing the thickest one of the four walls, which are in an envelope of two opening portions provided in the lens holder and which are perpendicular to a flat plate between the two opening portions, in a position which is opposite to the object lens with respect to the center line between a first support member and a second support member which resiliently support the lens holder therebetween and which is opposite to the object lens with respect to the flat plate.

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.
