ABSTRACT:
According to another aspect, an optical recording and/or reproducing apparatus includes a frame, a spindle motor, a pair of parallel guide rails, an optical pickup head, and a shield mounted on the guide rails. The shield extends a protection surface higher than a lens of the optical pickup head. The protection surface is in an optical disc region and lowers than the optical disc when the optical disc is supported on the spindle motor.
