    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: An optical pickup converts a laser beam from a semiconductor laser (1) into a parallel ray with a collimator lens (2), and divides it into a main beam (30), a sub-beam (+1st order component) (31), and a sub-beam (−1st order component) (32) with a gradient multiple-division type phase difference grating (3). After passing through a beam splitter (4), an objective lens (5) condenses the light beams on a track (61) of an optical disc (6), and the reflected light that has passed through the objective lens 5 is reflected at the beam splitter (4) and is guided into optical detectors (8A, 8B, and 8C) by a condensing lens (7). Accordingly, in a tracking error signal detecting method using the push-pull signals of the main beam and sub-beams, an offset produced by an objective lens shift or a disc tilt can be cancelled at low cost without lowering the efficiency of using light.

    摘要: A conductive rotator is immersed in a sample liquid in a sample container. A magnet is arranged at a specific distance from the rotation plane of the rotator in a direction of a rotating axis of the rotator so as to face the sample container. The magnet applies a magnetic field to the rotator from the outside of the sample container. A fluctuating magnetic field drive unit drives the magnet to apply the magnetic field that fluctuates in term of time to the rotator. Induced current is excited in the rotator by the fluctuating magnetic field. A rotating torque is provided to the rotator by the Lorenz interaction between the induced current and the fluctuating magnetic field, and as a result, the rotator rotates in the rotation plane. A viscosity detecting unit obtains the viscosity of the sample liquid based on a rotating state of the rotator and a time-fluctuating state of the fluctuating magnetic field.
