Abstract
An optical disk apparatus includes a light source, an objective lens, a slider to hold the lens, a suspension to support the slider, a mirror located below the slider, and a seek mechanism to move the mirror and the slider in the tracking direction of an optical disk to be used. The mirror upwardly reflects light traveling in a predetermined horizontal direction, thereby causing the reflected light to enter the objective lens arranged above the mirror. The mirror is rotatable about a prescribed axis for causing the reflected light to shift in the above-mentioned horizontal direction.
