Abstract
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.
