Optical pickup device and collimate lens

An optical pickup device which records or plays back information in or from an optical recording medium by condensing a luminous flux emitted from a light source onto the optical recording medium through a light-condensing optical system, the optical pickup device comprising:

• a first coma-aberration correction actuator including a first tilt drive portion configured to incline, in a first tilt direction, an objective lens for converging emitted light onto said optical recording medium;
• and
• a second coma-aberration correction actuator including a second tilt drive portion configured to incline, in a second tilt direction, a coma-aberration correction lens placed between said light source and a raising mirror for reflecting said emitted light toward said objective lens, wherein,
• said coma-aberration correction lens is a collimating lens configured to convert divergent light emitted from said light source into substantially-parallel light,
• said second coma-aberration correction actuator includes an elastic support spring, this elastic support spring has a center axis at least in the direction parallel to said optical recording medium and supports said coma-aberration correction lens at the opposite sides of said coma-aberration correction lens such that said coma-aberration correction lens can tilt about said center axis, and said second tilt drive portion drives said coma-aberration correction lens to tilt it about said center axis,
• said first coma-aberration correction actuator has two or more objective lenses intended for luminous fluxes with two or more wavelengths which are emitted from said light source, and is capable of driving said two or more objective lenses in three directions which are a focusing direction which is a direction perpendicular to said optical recording medium, a tracking direction which is a direction parallel to a radial direction of said optical recording medium, and said first tilt direction corresponding to a tilt direction which is a direction about an axis parallel to a tangential direction of said optical recording medium.
