Abstract
A data recording/reproduction apparatus is provided, which apparatus includes a spindle motor which is held by a base body and rotates an optical disk, an optical pickup which projects a laser beam into a spot on the optical disk for data recording/reproduction, first and second support mechanisms provided on the base body, and a seek mechanism which is held by the first and second support mechanisms so as to be freely tilted with respect to the base body and actuates the optical pickup in radial directions of the optical disk. The first support mechanism is vertically movable in directions of a thickness of the optical disk so that a tilt of the optical pickup with respect to the optical disk is adjusted.
