An optical pickup device includes a light source to emit light, an objective
lens
to focus the light on a recording medium to form a light spot, an optical path
changer on an optical path between the light source and the objective lens to change
the path of incident light, a chromatic aberration correction lens disposed on
an optical path between the light source and the objective lens, and a photodetector
to receive light which is reflected from the recording medium and is then incident
thereon through the optical path changer. The chromatic aberration correction lens
corrects a chromatic aberration occurring due to a change in the wavelength and/or
due to an increase in a wavelength bandwidth of the light. The chromatic aberration
correction lens includes at least two lenses such that a lens having a positive
power and a lens having a negative power are adjacent to each other.
