。An optical system consisting of an objective lens and a mirror, an elastic support for movably holding the objective lens and mirror, and a servo system to compensate for focusing errors and tracking errors to drive the objective lens and mirror. In an optical pickup device constituted by a drive mechanism, the optical system includes an objective lens barrel that holds the objective lens and has a light beam passage window, and a front mirror disposed coaxially inside the objective lens barrel. a mirror tube that holds the objective lens, a lens that deflects the axis of the light beam from the mirror, a parallel elastic support that movably holds the objective lens tube, and a parallel elastic support that movably holds the mirror tube. 1. An optical pickup device characterized in that it is constructed by alternately attaching support bodies.
