摘要： An optical pickup having a light-emitting element, an objective lens unit, a reflecting mirror and a light-receiving element, emits a beam onto an optical recording medium and uses a reflected beam to read recorded information. In the objective lens unit, a central part of a surface, facing the light-emitting element, of an objective lens disposed so that an optical axis is substantially aligned with a chief ray of the beam emitted by the light-emitting element, is a transmissive diffraction grating, and a central part of a surface of the objective lens that will face the optical recording medium is a convex mirror which bulges toward the light-emitting element. The reflecting mirror, which is annular and encompasses the optical axis of the objective lens, reflects toward the objective lens the beam from the light-emitting element that has passed through the transmissive diffraction grating and been reflected by the convex mirror. The light-receiving element receives first-order diffracted light, of the reflected beam from the recording medium, diffracted by the transmissive diffraction grating.

摘要： In an optical head operable to record to and read from an optical recording medium, a beam emitted by a light-emitting element is reflected toward the light-emitting element by a first reflective mirror, and this reflected beam is reflected toward the optical recording medium by a second reflective mirror and focused on a recording surface of the optical recording medium. In this case, the first reflective mirror blocks a principal ray of the beam traveling toward the optical recording medium from the second reflective mirror, and the second reflective mirror consists of a plurality of concentric annular mirrors centered on the principal ray of the beam and separated from each other by a predetermined interval.

摘要： A dichroic mirror is a wedge-shaped quadrangular prism whose cross-section is a trapezoid having an upper base d and a lower base d+Δd. The dichroic mirror receives on its top surface parallel light emitted from a collimating lens and reflects, off the top surface, most of the parallel light towards a wavelength plate. Moreover, the dichroic mirror transmits, through the top surface, part of the parallel light to output the part of the parallel light from a bottom surface facing the top surface toward a front monitor. The dichroic mirror has, on the bottom surface thereof, an inclination of an angle φ with respect to the top surface in a direction where a normal vector N of the bottom surface intersects with an xy-plane formed of: an optical axis x of incident light from the collimating lens; and an optical axis y of light emitted towards the wavelength plate.

An objective lens satisfies a relationship of tc>(t0+tn)/2 assuming that t0 denotes the thickness of a light transmitting layer from the outer surface of the multi-layer optical disc to an information recording surface having the largest light transmitting layer thickness, tn denotes the thickness of a light transmitting layer from the outer surface of the multi-layer optical disc to an information recording surface having the smallest light transmitting layer thickness and tc denotes the thickness of a virtual light transmitting layer at which the absolute value of a third-order spherical aberration is minimum when blue-violet laser light is incident as parallel light on the objective lens.
