    Abstract: A relative rotational angle of a rotary body is measured with respect to a reference angle. A disk rotates integrally with the rotary body. First openings are arranged about the entire circumference of the disk and spaced from one another by a predetermined pitch. A first detecting element detects the first openings and generates a first binary code. Second openings are arranged concentrically with the first openings. A second detecting element detects the second openings and generates a second binary code. A CPU computes a relative rotational angle of the rotary body in accordance with the first binary code and initializes the reference rotational angle of the rotary body in accordance with the second binary code. When the first detecting element generates the first binary code, the CPU determines the reference angle based on a combination of the first and second binary codes stored by a ROM.

    Abstract: A scanning optical system is provided with a light source, a deflector that deflects a light beam emitted from the light source to scan in a main scanning direction, a scanning lens that converges the light beam deflected by the deflector on an imaging surface to form a spot which scans on the imaging surface in the main scanning direction, and a mirror arranged between the deflector and the imaging surface, the mirror bending an optical path of the laser beam between the deflector and the imaging surface. With this structure, the reflecting surface of the mirror has a diffraction surface to compensate for lateral chromatic aberration generated by the scanning lens.

    Abstract: Disclosed is a laser scanning optical system wherein light emitted from a laser source is deflected by a polygonal mirror to a scanning target surface via an imaging optical system. The laser source, the polygonal mirror, and the imaging optical system are arranged such that a stationary ghost image formed by an m-th reflection surface is formed out of the light source side end of an effective scanning range on the target surface, and a stationary ghost image formed by an (m+1)-th reflection surface is formed out of the other end of the effective scanning range.

    Abstract: There is provided an optical system for an optical disc which requires a numerical aperture larger than or equal to 0.60. The optical system is provided with a light source, an objective lens, and a driving system that controls a position and an attitude of the objective lens. The driving system operates to move the objective lens in a direction perpendicular to a central axis of the objective lens for a tracking operation, and to change the attitude of the objective lens during the tracking operation so that the central axis on a light source side tilts toward the light source.
