摘要： An optical pickup includes a hologram element. The hologram element is provided with a hologram pattern including a splitting section for focus which splits light used for the detection of an FES and a splitting section for tracking which splits light used for the detection of a TES. The splitting section for tracking is formed in a region excluding a region interposed between a first virtual straight line and a second virtual straight line. The first virtual straight line is drawn on the hologram element in parallel to an X direction and passes through an optical axis of reflected light entering the hologram element in a state where the objective lens is in a neutral position, and the second virtual straight line is drawn in parallel to the first virtual straight line, while being spaced at a distance d from the first virtual straight line.

摘要： To read information from a target information recording surface reliably by canceling DC offsets in tracking-signal detection signals is provided. In effecting tracking servo by 3-beam method, auxiliary light receiving domains D3—1, D3—2, D8—1, D8—2 are provided. The auxiliary light receiving domain receives images formed by the light returned from a different information recording surface from the one targeted for reading. Sub beams of ± first-order diffracted light enter the light receiving domains D3, D8, D1, D10. With respect to the diffraction direction of the hologram, the auxiliary light receiving domains D3—1, D3—2 (D8 1, D8—2) are provided on both sides of the light receiving domain D3 (D8). Since signals are computed as: D8-(D8—1+D8—2); and D3-(D3—1+D3—2) with the internal connection, DC offsets can be canceled in RES signals (D1+D3, D8+D10) used in the DPP method.

摘要： A diffracting portion is disposed in an optical path between a light source and an optical disc. The diffracting portion diffracts the reflected light from recording layers of the optical disc toward a light receiving portion. The diffracting portion includes a first diffraction region having a first diffraction efficiency and a second diffraction region having a second diffraction efficiency lower than the first diffraction efficiency. The first diffraction region includes a FES diffracting portion and first to fourth TES diffracting portions. The second diffraction region includes fifth and sixth TES diffracting portions. First-order diffraction lights from the non-light-collecting recording layer enter on the fifth and the sixth TES diffracting portions, and are diffracted toward the light receiving portion by the fifth and the sixth TES diffracting portions.
