An optical pickup apparatus including a swing arm pivotably installed in a
tracking direction with respect to a disc, and an optical pickup unit
supported by the swing arm and driven in a focusing direction, wherein
the optical pickup unit includes a laser diode, an objective lens to
focus light emitted from the laser diode on a recording surface of the
disc, and a heat sink plate to dissipate heat generated from the laser
diode, wherein the heat sink plate is provided close to the disc so as to
be directly exposed to wind generated during rotation of the disc.
