Abstract
An optical recording/reproducing apparatus for recording/reproducing information onto/from an optical recording medium includes an optical element for condensing a light beam onto the recording medium. A detector coupled to the optical element detects a tilt condition between the recording medium and the optical element. The detector irradiates a detection beam onto the recording medium through the optical element, and detects the detection beam reflected by the recording medium through the optical element.
