摘要： The present invention provides an optical head for realizing the stable operation by controlling the temperature of the semiconductor laser to a low level by reducing the heat transfer rate from a laser driver IC to a housing in the vicinity of a semiconductor laser, and an optical disc drive using the same. It provides an optical head having a semiconductor laser and a photo detector arranged on one side with respect to a straight line through the center of an object lens of an object lens actuator and in parallel to the axis contacted with bearings, and a laser driver IC arranged on the other side with respect to the straight line. Thereby, the distance from the laser driver IC to the semiconductor laser can sufficiently be ensured so that the heat transfer rate from the laser driver IC to the housing can be reduced.

摘要： In a disc driving apparatus, wherein a laser diode and a laser driver circuit board are mounted on a pickup housing in thermal contact therewith and are disposed adjacent to each other, a heat separation member is provided between the laser diode and the laser driver circuit board for effecting thermal separation therebetween, thereby reducing the thermal interference between the heat-generating elements that are adjacent to each other in the optical pickup. This makes it possible to protect the heat-generating elements from being deteriorated, leading to a reduction in the lifetime thereof, as well as, to improve the reliability thereof.

摘要： In a laser welding method, detachment is suppressed and dislocation of an optical component is reduced by improving adhesiveness of an interface of a welded part to thereby improve yield and reliability of an optical pickup device. A manufacturing method of an optical pickup device includes: a step of bringing the optical component into contact with the holding member; a step of irradiating laser light; and a step of melting the holding member through the irradiation to weld the holding member to the optical component, wherein before the laser light is irradiated, surface roughness of a portion of the optical component to be welded is greater than surface roughness of the holding member in contact with the portion, whereby the melted holding member enters into an uneven part on a front surface of the optical component, improving adhesion strength.
