摘要： In an eccentricity measuring method according to the present invention, a first position of a light source image formed by reflection at one optical surface is measured (S2), a predetermined second position related to another optical surface is measured (S3), and a relative eccentricity between both optical surfaces is calculated based on the first and second positions (S5). Therefore, the eccentricity measuring method enables measurement of eccentricity by a same measurement optical system regardless of a radius of curvature of an optical surface of an optical element.

摘要： A recorder has a recording medium for information recording, a light source, an optical system, a slider, and an optical waveguide. To the optical system, light from the light source enters, and the slider moves relative to the recording medium while not in contact therewith. The optical waveguide is arranged at position facing the recording medium in the slider so that light entering from the optical system is irradiated on the recording medium. Where the mode field diameter of the optical waveguide on the light output side is d and the mode field diameter thereof on the light input side is D, the mode field diameter is converted by smoothly changing the diameter of the optical waveguide to satisfy D>d.
