摘要： An optical element includes a microlens array on which plural microlenses are arranged. The microlens array includes plural areas whose microlenses have different curvature radii per area. The plural areas are configured so that the farther the area exists from the center of the microlens array, the smaller the curvature radius of the microlenses arranged on the area is.

摘要： An optical element includes first and second microlens array units on which microlenses are arranged. The microlenses are formed by lens contour having a polygonal shape in a plan view. The first and second microlens array units are arranged opposite to each other at a position where a distance between the first and second microlens array units is at least longer than a focal distance of the microlens, and are formed so that a direction of vertices of the lens contour of the microlens arranged on the first microlens array unit is different from a direction of vertices of the lens contour of the microlens arranged on the second microlens array unit. According to the above optical element, it is possible to appropriately suppress an influence of shift of the position between the first and second microlens array units, and it becomes possible to produce the optical element with ease.

摘要： An optical pickup reads or records information on a recording surface of a first optical record medium or a second optical record medium, each of which has a protection film different in thickness from each other. The optical pickup includes: a light beam source for emitting a light beam; a dividing unit for dividing the light beam into a non-diffracted light, which is a portion of the light beam other than diffracted lights, and a first order diffracted light; and a converging unit for converging the non-diffracted light and the first order diffracted light. Further, an optical path length between the light beam source and the converging unit is determined so that the non-diffracted light is converged onto the recording surface of the first optical record medium and a spherical aberration of the non-diffracted light converged onto the recording surface of the first optical record medium is minimized. And the dividing unit is constructed so that the first order diffracted light is converged onto the recording surface of the second optical record medium and a spherical aberration of the first order diffracted light converged onto the recording surface of the second optical record medium is minimized.

摘要： The present invention makes possible a compact optical pickup device that eliminates effects due to the position where a sub beam is projected during tracking compensation, and provides for stable tracking compensation.A diffraction grating 12 in the optical pickup device PU gives an astigmatism to a sub beam (either of ±1-dimensional light), and shines that sub beam onto an optical disc DK. Also, a tracking error signal Ste is obtained by subtracting a push-pull signal PPsub that corresponds to a sub beam from a push-pull signal PPmain that corresponds to a main beam (0-dimensional light), and tracking compensation is performed based on that tracking error signal Ste.

摘要： An optical pickup projects laser beams having the first to the third wavelengths, in response to the type of a recording medium which is an object to which recording or reproduction is to be performed, and reflecting light from the recording medium is received by a light-detecting element. In order to reduce the sizes of the optical pickup, light of the second and the third wavelengths is generated by a single dual-wavelength light source, and reflecting light of all the wavelengths is to be received by the single light-detecting element. A hologram element giving different optical effects to light of each wavelength is arranged between the light irradiating means and the light-detecting element. Thus, appropriate information recording and reproduction can be performed by using light of each wavelength.
