Abstract:
An optical disc apparatus, presenting recording quality without degradation by an extreme temperature rise in an objective-lens drive mechanism in an optical pickup, includes a mechanical chassis on which a disc rotation mechanism, an optical pickup, and a transfer mechanism are mounted, a decorative plate that is a plate-shaped member located between the disc and the optical pickup and fixed on the mechanical chassis, a disc tray for loading and removing the disc, a circuit board for operation control, and an apparatus housing containing the components. A recess is formed in an indented shape in a portion of the mechanical chassis facing an outer peripheral region of the disc recording surface. An incline is formed in a position close to an opening of the disc tray for mounting the mechanical chassis and opposite the outer peripheral region of the disc recording surface, and slopes gently down to the recess.
