摘要： The present invention relates to an optical pick, an optical drive device, and a light irradiation method capable of suppressing a generated amount of shift Δx of a spot position.
The optical pickup irradiates an optical recording medium through a common objective lens which irradiates a first light for use in information recording in or information reproduction from a recording layer and a second light different from the first light, the optical recording medium includes a reference surface having a reflection film in which a position director is formed in a spiral form or the like form, and the recording layer which is provided in a layer position different from the reference surface and in which a mark corresponding to irradiation of light is formed and hence information is recorded. The optical pickup adjusts a focusing position of the first light having passed through the objective lens by changing collimation of the first light entering the objective lens, thereby suppressing the shift Δx of a spot position between the first light and the second light which occurs due to the eccentricity of the optical recording medium. A magnification of the second light is within a magnification range of the first light.

摘要： In optical recording and/or reproduction using an SIL optical system that performs a tilt servo using light for recording and/or reproduction, the SIL and an optical recording medium have a high probability of colliding with each other before the tilt servo is started. To prevent the collision, an optical recording/reproduction method performs a gap servo that controls a gap between a surface of an optical recording medium and a bottom surface of an SIL using reflected light that is generated from light traveling from the bottom surface of the SIL and reflecting on the optical recording medium, a focus servo that controls a distance between a focal point of the light and the bottom surface of the SIL, and a tilt servo that controls a tilt of the bottom surface of the SIL relative to the surface of the optical recording medium using the reflected light. The method includes the acts (A), (B), and (C), which are performed sequentially: (A) starting the gap servo with the gap being set larger than when optical recording and/or reproduction is performed, and shifting the focal point to an optical recording medium side from the bottom surface of the SIL, (B) starting the tilt servo, and (C) setting the gap smaller and arranging the SIL at a predetermined position.

摘要： An optical pickup device comprises a diffraction grating (12) for branching an optical beam outputted from a light source into at least three optical beams. The diffraction grating (12) is divided sequentially into first through forth regions having periodic structures of different phases by division lines extending in parallel with the tangent of track of an optical information recording medium. Phase of the periodic structure in the second region (12B) is different by about 180 degrees from that of the periodic structure in the third region (12C), and the phase of the periodic structure in the first region (12A) is different by about 180 degrees from that of the periodic structure in the fourth region (12D).
