Surface selection mechanism for optical storage system

摘要

A surface selection mechanism is disclosed for an optical disk storage system. The mechanism comprises a linearly movable slider having a first and second mirror mounted side by side thereon. The first and second mirrors have reflective mirrors positioned at right angles with respect to each other. The mechanism includes apparatus for positioning the slider so that either the first or second mirror is positioned at the optical axis of a light beam to direct the light beam at either a first or a second recording surface of a double sided disc.
