Patent ID: 8369193

Claim:
An optical pickup apparatus configured to apply a light flux to an information recording medium to be rotated and detect the light flux reflected from the information recording medium, comprising: a first objective lens configured to focus the light flux on the information recording medium; a second objective lens configured to focus the light flux on the information recording medium; a lens holder including a first lens barrel having the first objective lens mounted on an end face thereof and a second lens barrel having the second objective lens mounted on an end face thereof; an actuator unit having the lens holder mounted thereon; and a housing having the actuator unit mounted thereon, the first objective lens and the second objective lens each being mounted on the lens holder such that a direction in which a wavefront of coma aberration of the first lens is most advanced in phase and a direction in which a wavefront of coma aberration of the second lens is most advanced in phase are both aligned with a radial direction of the information recording medium, the actuator unit being mounted on the housing such that an optical axis of the first objective lens is inclined in the radial direction at an inclination angle of the optical axis thereof toward a recording surface of the information recording medium which angle is required to cancel coma aberration of the first objective lens to the recording surface.
