It is an object of the present invention to provide an optical pickup
apparatus appropriate for the notebook PC that can prevent structural
resonance of the lens holder by arranging the focus coil and the tracking
coil in a way to stabilize the weight balance, enable the tilt servo, and
be composed in an extremely reduced thickness. An optical pickup
apparatus composed to adjust the irradiation position of light beam to an
optical disk by displacing an objective lens through a driving control of
a lens holder holding the objective lens with a moving coil method,
wherein an objective lens driving section is composed by arranging and
fixing focus coils 7a, 7b so that a pair of coil main bodies be
symmetrical about the objective lens 4 arranged at the middle of the lens
holder 4, and arranging a pair of tracking coils 8a, 8b, 8c, 8d at both
sides of the respective focus coils.
