ABSTRACT:
An optical disk player is provided, which includes a drive chassis provided with: a spindle motor for driving a turntable on which an optical disk is supported; a photopickup with a rack which is movable while being guided in the direction of approaching/separating with respect to the turntable; and a feed motor for applying a driving force to the rack. The rack is disposed on an operating line crossing the spindle motor, and an end portion of the rack is positioned within the area of a corner portion of a quadrilateral circumscribed in the outer circumference of the optical disk when the photo-pickup is moved to a position remotest from the turntable, thus, no hindrance is created by the thus projected portion of the rack because that area is a dead space of the player.
