Patent ID: 7778142

Claim:
An optical pickup apparatus for recording and/or reproducing data on a recording medium, the optical pickup apparatus comprising: two semiconductor lasers as light sources for emitting light; a laser driver for controlling light emitting operations of the two semiconductor lasers; a first housing to which the laser driver is attached; and a second housing to which the two semiconductor lasers are attached, wherein the first housing has two side surfaces which are adjacent and perpendicular to each other, the second housing has a recess comprising two side surfaces which are parallel to the two side surfaces of the first housing, the first housing is arranged in the recess of the second housing so that the two side surfaces thereof are separated from the two side surfaces of the second housing and is connected to the second housing by a heat-insulating connecting member so that a space having an L-shaped cross section is formed between the first housing and the second housing, and the two semiconductor lasers are arranged so as to be adjacent to the laser driver with the space having the L-shaped cross section therebetween.
