摘要： A high-density focusing objective lens having a high numerical aperture (NA), which can be easily manufactured by an existing technique, and an optical pickup using the objective lens for high-density recording. The objective lens includes a first transmitting portion placed at a relatively near-axis region from the optical axis to divergently transmit an incident light beam; a first reflecting portion to divergently reflect the incident light beam, the first reflecting portion faces the first transmitting portion; a second reflecting portion, formed at a relatively far-axis region around the first transmitting portion that focuses and reflects the light reflected from the first reflecting portion; and a second transmitting portion, formed at a relatively far-axis region around the first reflecting portion, that refracts and transmits the light beam focused by the second reflecting portion as a peripheral light beam, wherein the maximum angle &agr; between the optical axis and the peripheral light beam satisfies the condition of 30° ≦&agr;≦65°. The optical pickup further includes the previously mentioned objective lens as a second objective lens, which is optionally placed into the optical path between a first objective lens and an optical medium. As a result, the NA of the objective lens unit can be increased up to 0.85 while the working distance d2 is maintained to be 0.2 mm.

摘要： An optical pickup in which a light receptor and a light transmitter are integrated with a catadioptric objective lens. The optical pickup includes a unit for emitting laser light to a recording medium and detecting the light reflected from the recording medium. The catadioptric objective lens includes a first reflective area for reflecting the light incident from the unit, a focusing area for focusing the light incident from the unit as a focused spot, and a second reflective area for reflecting the light reflected from the first reflective area toward the focusing area. The first reflective area and the focusing area form a first surface of the catadioptric objective lens while the second reflective area is a part of a second surface of the catadioptric objective lens located in the vicinity of the unit. The light from the unit is incident to the catadioptric objective lens via portions of the second surface other than the second reflective area The optical pickup uses compact and light-weight components creating a thinner optical pickup suitable for use in slim devices such as notebook computers.

摘要： A recording/reproducing apparatus including an optical pickup compatible with a plurality of optical recording media each using light of a different wavelength. The optical pickup includes at least one light source, an objective lens having a function of focusing light emitted from the light source into the optimal light spot on an information recording surface of one of the plurality of the optical recording media, and a light detector to detect light transmitted through the objective lens after being reflected from the information recording surface of the optical recording medium on which the light spot is formed. The objective lens has an inner area, an annular lens area and an outer area such that the annular lens area divides the inner area from the outer area and has a ring shape centered at a vertex. The inner area, the annular lens area and the outer area have aspherical surface shapes to focus light transmitted through the inner area and the outer area into a single light spot by which information can be read from the information recording surface of a relatively thin first optical recording medium and scatter light transmitted through the annular lens area located between the inner area and the outer area so that information cannot be read from the information recording surface of the first optical recording medium, during reproduction of the first optical recording medium. The inner area and the annular lens area transmit light into a single light spot by which information can be read from the information recording surface of a relatively thick second optical recording medium and scatters light transmitted through the outer lens area so that information cannot be read from the information recording surface of the second optical recording medium, during reproduction of the second optical recording medium.
